Sliced and Diced: PTAB Decision Remanded for Further Analysis

by Thomas DaMario | Oct 6, 2022 | Patents

In an appeal from a Patent Trial & Appeal Board final written decision, the US Court of Appeals for the Federal Circuit affirmed the Board’s decision to include certain evidence first presented in the petitioner’s Reply but vacated the Board’s obviousness decision for a failure to fully and particularly set out the bases for its decision. Provisur Technologies, Inc. v. Weber, Inc., Case Nos. 21-1942; -1975 (Fed. Cir. Sept. 27, 2022) (Prost, Reyna, Stark, JJ.)

Provisur Technologies owns a patent directed to classifying slices or portions cut from a food product according to an optical image of the slice. The patent explains that certain meat products, such as bacon or cold cuts, are sold in groups of slices according to particular weight requirements. The specification also teaches that the arrangement of the slices according to quality is desirable. The independent claims are directed to an image processing system arranged above a weigh conveyor that is capable of categorizing slices by determining the surface area and fat-to-lean ratios of the slices based on pixel-by-pixel image data.

Weber petitioned for inter partes review of the patent, alleging that the claims were obvious over various prior art references. Provisur, in its Patent Owner Response, disputed Weber’s assertion that the prior art references disclosed the claimed digital imaging receiving device capable of determining a surface area from pixel-by-pixel image data. During deposition of Weber’s expert, Provisur probed the expert’s knowledge of various camera models available as of the priority date. This prompted Weber to introduce a data sheet on redirect showing various models of cameras, including a comparison between those disclosed in the prior art references and those disclosed as exemplary in the patent. Provisur moved to exclude the datasheet, but the Board concluded that the evidence was highly probative and allowable because it was submitted in response to an argument that Provisur advanced in its Patent Owner Response. The Board also found that the independent claims and various dependent claims were invalid as obvious over the references cited by Weber.

Provisur appealed the admission of the datasheet and the Board’s determination on obviousness. Regarding the evidentiary issue, the Federal Circuit found that the Board did not abuse its discretion by considering the datasheet, noting that it was reply evidence responsive to Provisur’s arguments that the prior art did not disclose a digital camera: “Importantly, Weber’s invalidity theories did not change, nor did the reply fill any holes in Weber’s petition.” Furthermore, the Court observed that Provisur had an opportunity to respond both by cross-examining Weber’s expert and in a sur-reply to the Board.

Regarding the Board’s obviousness determination, Provisur argued that the Board erred by failing to explain its rationale for how the prior art combinations specifically taught the claim element of “determining a surface area of the top slice from the [pixel-by-pixel image] data [of a top slice of the stack].” Under the Administrative Procedure Act (APA), the Board must fully and particularly set out the basis upon which it reached its [...]

Standard Computer Equipment Can Support Inventive Concept under Alice Step 2

by McDermott Will & Emery | Oct 6, 2022 | Patents

The US Court of Appeals for the Federal Circuit overturned a district court dismissal of a patent case for errors in analyzing the claims’ patent eligibility under Alice. The Court found that regardless of whether the claimed invention was abstract under step 1, the invention claimed specific improvements rendering it patent eligible under step 2. Cooperative Entertainment, Inc. v. Kollective Technology, Inc., Case No. 21-2167 (Fed. Cir. Sept. 28, 2022) (Moore, C.J.; Lourie, Stark, JJ.)

Cooperative Entertainment sued Kollective Technology for infringement of several claims of Cooperative’s patent directed to structuring a peer-to-peer (P2P) dynamic network for distributing large files. After Kollective filed a motion to dismiss under Fed. R. Civ. P. 12(b)(6) arguing that all of the patent claims were ineligible under 35 U.S.C. § 101, Cooperative filed an amended complaint. Kollective refiled its motion to dismiss, and the district court granted the motion, holding the challenged claims ineligible under § 101. Cooperative appealed.

The patent relates to systems and methods of structuring a P2P dynamic network for distributing large files, specifically videos and video games. The patent specification explains that in prior art systems, video streaming was controlled by content distribution networks (CDNs), with content “distributed directly from the CDN server originating the content.” In contrast, the challenged claims recite methods and systems for a network in which content distribution occurs “outside controlled networks and/or [CDNs]” (emphasis added), and therefore outside a “static network of controlled systems.” Dynamic P2P networks comprising “peer nodes,” which consume the same content contemporaneously, transmit content directly to each other instead of receiving content from the CDN. The claimed P2P networks use “content segmentation” to segment a video file into smaller clips and distribute it piecemeal. Viewers can obtain individual segments as needed, preferably from other viewers. The disclosed segmentation techniques include “CDN address resolution, trace route to CDN and the P2P server manager, dynamic feedback from peers reporting traffic rates between individual peer and its neighbors, round-robin, other server side scheduling/resource allocation techniques, and combinations thereof” (emphasis in original).

The Federal Circuit applied the two-step Alice framework: (1) determining whether the claim is “directed to” a “patent-ineligible concept,” such as an abstract idea, and if it is, (2) examining “the elements of the claim to determine whether it contains an ‘inventive concept’ sufficient to ‘transform’ the claimed abstract idea into a patent-eligible application.” Step 2 examines whether the claim elements, individually and as an ordered combination, contain an inventive concept that more than merely implements an abstract idea using “well-understood, routine, [and] conventional activities previously known to the industry.”

Under Alice step 1, the district court had held that the “focus of the [] patent” is the abstract idea of “the preparation and transmission of content to peers through a computer network.” The Federal Circuit disagreed, concluding that regardless of whether the invention could be reduced to an abstract concept, under step 2 the claims contained several alleged inventive concepts that the specification touted as specific improvements in the distribution of data [...]

The Board Is Back in Town: Arthrex Can’t Save Untimely Motions to Terminate

by Mike Baldwin | Sep 29, 2022 | Patents

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) unpatentability finding and denial of a motion to terminate, finding that the Board had already issued final written decisions that were not vacated at the time the Board denied the parties’ motion to terminate. Polaris Innovations Ltd. v. Derrick Brent, Deputy Under Secretary of Commerce for Intellectual Property and Deputy Director of The United States Patent and Trademark Office, Case No. 19-1483 (Fed. Cir. Sept. 15, 2022) (Prost, Chen, Stoll, JJ.)

Polaris owns two unrelated patents directed to computer memory. The first patent relates to improved control component configuration, and the second patent relates to a shared-resource system in which logical controls are used to manage resource requests. In 2016, Polaris filed a complaint accusing NVIDIA of infringing both patents. NVIDIA responded by filing petitions for inter partes review (IPR) against each patent. In 2017, the Board issued its final written decisions, finding the challenged claims of both patents unpatentable. Polaris appealed.

The Federal Circuit vacated the Board’s decision in view of Arthrex, Inc. v. Smith & Nephew, Inc. (Arthrex I). On remand, the Board administratively suspended the IPR proceedings pending potential Supreme Court review of Arthrex I. During the administrative suspension, Polaris and NVIDIA filed a joint motion to terminate the proceedings. While those motions were pending, the Supreme Court vacated Arthrex I, substituting an alternative remedy for violation of the Appointments Clause in United States v. Arthrex, Inc. (Arthrex II). In view of Arthrex II, the Supreme Court vacated the Federal Circuit’s vacatur of the Board’s final written decision, thus reinstating those decisions.

On remand to the Board, Polaris argued that the Board should grant Polaris’s then-pending motion to terminate. The Chief Administrative Law Judge responded that termination was not appropriate because the Supreme Court’s decision meant that the “final written decision in each of these cases is not vacated, and it is not necessary for the Board to issue a new final written decision in either of these cases.” Polaris filed a request for Director rehearing. The Director denied rehearing. Polaris appealed.

Polaris argued that the Board erred by failing to grant the joint motions to terminate filed in both proceedings before the Board on remand. Relying on 35 U.S.C. § 317, the Federal Circuit explained that motions to terminate should be granted “unless the Office has decided the merits of the proceeding before the request for termination is filed.” The Court found that the Board had already decided the merits of the cases in final written decisions that were not vacated at the time the Board made its decision denying Polaris’s motions to terminate. The Court therefore affirmed the Board’s decision that termination was inappropriate.

Polaris also raised two claim construction arguments. Polaris argued that the Board misconstrued the term “memory chip” in the IPR involving one of the challenged patents and misconstrued the term “resource tag buffer” in the IPR involving the [...]

Claim at Issue Must Be Substantively Allowable to Qualify for PTA

by Samoneh (Sammy) Schickel | Sep 22, 2022 | Patents

The US Court of Appeals for the Federal Circuit affirmed two district court decisions, finding that a patent owner who only partially prevailed in one of two appeals was not entitled to any additional patent term adjustments (PTAs) from the US Patent & Trademark Office (PTO) under 35 U.S.C. § 154(b)(1)(C) during the pendency of their district court appeals. SawStop Holding LLC v. Vidal, Case No. 2021-1537 (Fed. Cir. Sept. 14, 2022) (Newman, Linn, and Chen, JJ.)

SawStop owns two patents directed to saws with a safety feature that stops a power-saw blade upon contact with flesh. During prosecution of the application for one of the patents, SawStop appealed an obviousness rejection to the Patent Trial & Appeal Board (Board). The Board affirmed the obviousness rejection but on new grounds. The patent ultimately issued after SawStop amended the claim at issue to overcome the obviousness rejection.

Similarly, during prosecution of the application for the second patent, independent claim 1 was rejected as being anticipated and for obviousness-type double patenting while dependent claim 2 was rejected as anticipated. SawStop appealed the rejections. The Board affirmed both rejections of claim 1 but reversed the rejection of claim 2. SawStop subsequently challenged the Board’s anticipation rejection of claim 1 before the US District Court for the District of Columbia, which reversed the anticipation rejection. SawStop did not challenge the obviousness-type double patenting rejection. On remand to the Board, SawStop cancelled claim 1 and rewrote claim 2 as an independent claim. A patent subsequently issued.

Since issuance of both patents was delayed by appeals before allowance, SawStop requested PTAs under Section 154(b)(1)(C):

Subject to the limitations under paragraph (2), if the issue of an original patent is delayed due to … (iii) appellate review by the Patent Trial and Appeal Board or by a Federal Court in a case in which the patent was issued under a decision in the review reversing an adverse determination of patentability, the term of the patent shall be extended 1 day for each day of the pendency of the proceeding, order, or review, as the case may be.

The Board granted PTA “for the delay incurred in the successful reversal of the rejection of claim 2” of the second patent but denied additional PTA for both patents resulting from the appeals. SawStop filed suits in the US District Court for the Eastern District of Virginia, challenging the Board’s decision. The court granted summary judgment in favor of the PTO in both suits. SawStop then appealed to the Federal Circuit.

The Federal Circuit affirmed, finding that SawStop was interpreting Section 154(b)(1)(C) too broadly. SawStop argued in part that any examiner rejection overturned on appeal qualified as “a reversal of a determination of patentability.” The Court rejected this argument, explaining that the Board’s adverse determination of unpatentability remained before and after the appeal to the Board. That is, “the reversal of a ‘determination of patentability’ requires a determination that the claim in question is substantively allowable, not just free of [...]

CAFC Pulls Final Loose Thread in Nike-Adidas Patent Row

by Paul Devinsky | Sep 22, 2022 | Patents

Issuing a third and final decision, the US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) decision invalidating the last remaining claim of a Nike footwear textile patent. Nike, Inc. v. Adidas AG, Case No. 21-1903 (Fed. Cir. Sept. 1, 2022) (Prost, Chen, Stoll, JJ.) (non-precedential)

Adidas filed for inter partes review of a patent owned by Nike relating to a knitted shoe upper. After lengthy litigation, including two prior appeals to the Federal Circuit, all claims of the Nike patent were invalidated except for one substitute claim. In its second appeal, Nike successfully argued that the Board did not provide Nike an opportunity to respond to a patentability issue raised sua sponte by the Board, which included reference to a knitting textbook. On remand from the second appeal, the parties were given the opportunity to brief the Board on this new reference and argue which party bears the burden of persuasion for the patentability issue raised sua sponte by the Board.

On the merits, the Board determined that the knitting textbook did teach the disputed limitation, agreeing with adidas that a skilled artisan would have understood the textbook to teach the contested limitation, and that there was adequate reason to combine the textbook’s teachings with those of the other prior art references. The Board also concluded that the burden of persuasion must fall on the Board itself when it raised the patentability issue sua sponte. Nike appealed, arguing that the Board effectively placed the burden of persuasion on Nike.

The Federal Circuit first addressed the burden of persuasion as it relates to the grounds first raised by the Board. The Court found that the Board juxtaposed its arguments with adidas’s and that they both relied on the same disclosures and arguments. Because the Board and adidas’s arguments mirrored each other, the Court found it unnecessary to determine whether the petitioner or the Board bears the burden of persuasion. The Court also rejected Nike’s argument that the Board effectively shifted the burden to Nike by stating in its opinion that Nike’s arguments were “unpersuasive” and “inadequate.” The Court cited to its 2016 holding in In re Magnum Oil Tools International, in which it explained that the Board’s language is not the concern but rather the actual placement of the burden of persuasion. The Court found that both the Board and adidas met the burden, and that the burden was not shifted to Nike.

Turning to the Board’s obviousness determinations, the Federal Circuit rejected all of Nike’s arguments. First, Nike argued that the knitting textbook did not teach the claimed method of creating apertures in the fabric by omitting stitches. The Court found that the Board relied on specific disclosures in the reference describing the use of empty needles to product “loop displacement.” Nike also argued that there was no motivation to combine the textbook reference with the other two references and that the Board could not rely on “common sense” [...]

Sometimes Inactions Speak Louder Than Words

by Sarah J. Fischer | Sep 22, 2022 | Patents

The US Court of Appeals for the Federal Circuit affirmed a decision granting summary judgment in favor of the US Patent & Trademark Office (PTO) regarding the propriety of imposing a restriction requirement on a pre-General Agreement on Tariffs and Trade (GATT) patent. Hyatt v. PTO, Case No. 2021-2324 (Fed. Cir. Sept. 8, 2022) (Moore, Prost, and Hughes, JJ.)

This action arose from the prosecution of a pre-GATT application that claimed priority to applications filed as early as 1983. The issue stems from changes to US patent law limiting patent terms to 20 years from their filing date. The old law provided a grant that lasted 17 years from a patent issuance. As the Federal Circuit noted in early litigation involving Gilbert Hyatt, tying patent term to the grant date “incentivized certain patentees to delay prosecuting their patents by abandoning applications and filing continuing applications in their place.” But the change in law left a gap for so-called transitional applications—those filed but not yet granted before the new law took effect. This “‘triggered a patent application gold rush in the spring of 1995’ by applicants who wanted their patent claims to be governed under the [old law] … This gold rush is ‘often referred to as the ‘GATT Bubble.’’”

Hyatt, a prolific inventor, is named in a series of pre-GATT applications filed in 1995 during the GATT bubble. Since then, he has continued to prosecute these applications. As a result of various litigations, the PTO stayed the prosecution of many of these applications between 2003 and 2012. In 2013, over Hyatt’s objections, the PTO required him to select eight claims from an application containing 200 for prosecution. In 2015, the PTO issued a non-final rejection on said claims. Hyatt responded by essentially rewriting the claims in their entirety. The examiner then issued a restriction requirement between the original and amended claims, which would require Hyatt to submit a new application with the new claims, which would be subject to the new law. The restriction requirement was based on the “applicant-action exception,” which allowed the PTO to issue a restriction requirement when the examiner could not have previously made one because of the actions of the applicant. The authority for the PTO action was rooted in Rule 129 (b)(1) (ii), which in relevant part provides:

(1) In an application … that has been pending for

at least three years as of June 8, 1995 … no requirement

for restriction . . . shall be made or maintained

in the application after June 8, 1995, except where:

…

(ii) The examiner has not made a requirement for

restriction in the present or parent application

prior to April 8, 1995, due to actions by the applicant

…

After the PTO issued a restriction requirement, Hyatt filed an action in the US District Court for the Eastern District of Virginia, alleging that the PTO violated the Administrative Procedure Act because the restriction requirement was arbitrary, capricious, an abuse of discretion or otherwise not in [...]

No Second Bite at the Apple: Dismissal under Duplicative-Litigation Doctrine

by Art Dykhuis | Sep 22, 2022 | Patents

The US Court of Appeals for the Federal Circuit affirmed a district court’s dismissal of a second case between the same parties and asserting the same patent under the duplicative-litigation doctrine. Arendi S.A.R.L. v. LG Elecs. Inc., Case No. 2021-1967 (Fed. Cir. Sept. 7, 2022) (Prost, Chen, Stoll, JJ.)

Arendi sued LG and others for infringement of several patents. Pursuant to Delaware’s local rules requiring identification of accused products, Arendi identified hundreds of LG products as infringing four asserted claims of the patent relevant on appeal. For those accused products, Arendi provided one “exemplary” infringement claim chart for LG’s Rebel 4 phone. LG objected to Arendi, stating that it should have provided charts for all accused products.

As the litigation proceeded, the parties agreed on eight products as representative but, despite LG’s repeated objection, Arendi did not provide claim charts for any additional products during fact discovery. Instead, Arendi’s opening expert report on infringement provided claim charts for seven non-Rebel 4 representative products for the first time. LG moved to strike those portions of the expert report. The district court granted that motion. Arendi did not supplement its claim charts in response to the court’s order and instead filed another complaint in Delaware, thus creating a second concurrent case asserting the same patent against LG. After the district court granted LG’s motion to dismiss the second suit, Arendi appealed.

The Federal Circuit explained the standard for assertion of the duplicative-litigation doctrine, which “prevents plaintiffs from ‘maintain[ing] two separate actions involving the same subject matter at the same time in the same court … against the same defendant.’” Whether two cases involve the same subject matter depends on the extent of factual overlap of the asserted patents and accused products. There was no dispute that the same patent was asserted in both cases, but Arendi disputed that the cases involved the same accused products, citing the district court’s order striking its expert report as evidence that the non-Rebel 4 products were not at issue in the first case.

Like the district court, the Federal Circuit disagreed. The Court distinguished between accusing products and satisfying discovery obligations regarding those products. Arendi listed the non-Rebel 4 products in its disclosure of accused products, served interrogatories about them, received discovery on them and included non-Rebel 4 products in its expert report. Thus, even though Arendi “failed to fulfill its discovery obligations” as to those products, which made its expert report untimely, the non-Rebel 4 products were still accused, at issue and litigated in the first case. Thus, dismissal of the second case under the duplicative-litigation doctrine was not an error.

Practice Note: In a footnote, the Federal Circuit acknowledged the similarity of the duplicative-litigation doctrine to res judicata (claim preclusion). Although both doctrines involve an inquiry into whether claims in the second suit are repetitious, unlike res judicata, the duplicative-litigation doctrine does not require a final judgment in the first case.

It Can Take Three Appeals to Make a Claim Construction Go “Right”—or Three Bites by Apple

by McDermott Will & Emery | Sep 22, 2022 | Patents

In a nonprecedential opinion on remand from the US Court of Appeals for the Federal Circuit and a US Patent & Trademark Office (PTO) Director-granted request for review, the Patent Trial & Appeal Board (Board) reconstrued claim terms it had previously construed in consideration of the patent specification, prosecution history and Federal Circuit construction of similar terms in a related case. Apple Inc. v. Personalized Media Communications, LLC, IPR2016-00754, IPR2016-01520 (P.T.A.B. Sept. 8, 2022) (Turner, APJ.)

In March 2016, Apple filed a petition to institute an inter partes review (IPR) against a patent (’635 patent) owned by Personalized Media Communications, LLC (PMC). After PMC filed its Patent Owner Preliminary Response (POPR), the Board instituted the IPR on some, but not all, of Apple’s requested grounds. Per Board procedure, PMC filed its Patent Owner Response (POR) and a contingent motion to amend its patent’s claims. In response, Apple filed a reply and an opposition to the contingent motion, and PMC filed a reply to Apple’s opposition. After oral argument the Board issued a Final Written Decision (754-FWD) finding all challenged claims unpatentable and denying the contingent motion to amend. PMC first sought rehearing of the Board’s decision and, after rehearing was denied, appealed the Board’s decision to the Federal Circuit.

Similarly, in July 2016, Apple filed another petition against the same PMC patent. After considering PMC’s POPR, the Board instituted an IPR on some of Apple’s requested grounds. PMC again filed a POR and a contingent motion to amend, to which Apple filed a reply and opposition (to which PMC filed its reply and Apple a sur-reply). Again, the Board held an oral hearing and issued a Final Written Decision (FWD) finding all challenged claims unpatentable and denying the contingent motion to amend. PMC again sought rehearing of the Board’s decision and, after rehearing was denied, appealed the Board’s decision to the Federal Circuit.

On appeal of each proceeding, PMC moved, and the Federal Circuit granted remand in light of and consistent with the 2021 Supreme Court decision in U.S. v. Arthrex, Inc., where a five-justice majority found that the appointment of Board administrative patent judges was unconstitutional and a seven-justice majority concluded that the remedy was to vest the PTO Director with authority to overrule Board decisions.

On remand to the PTO, PMC filed a request for director review, which the Commissioner for Patents (performing the functions and duties of the PTO Director) granted. The Commissioner’s Granting Order agreed with PMC’s argument that the Board, in these two cases, had construed the claim terms “encrypted” and “decrypted” in a manner that could include “scrambling and descrambling operations on digital information, but could also include … on analog information” and was inconsistent with the Federal Circuit’s partial reversal of the Board’s construction in yet another IPR proceeding (755-IPR regarding another related PMC patent) between Apple and PMC. As to the related patent IPR, the Federal Circuit ultimately construed “encrypted digital information transmission including encrypted information” as “… limited [...]

Present-Tense Claim Terms Not Sufficient to Require Actual Operation

by Alexander P. Ott | Sep 15, 2022 | Patents

The US Court of Appeals for the Federal Circuit affirmed a US International Trade Commission (Commission) decision that found no violation of Section 337 due to noninfringement. The Court disagreed with the Commission that the use of present-tense claim terms required actual operation to be shown to prove infringement, but nevertheless affirmed the Commission’s finding because the patentee failed to establish that the accused products were capable of carrying out the claimed functionality. INVT SPE LLC v. ITC, Case No. 20-1903 (Fed. Cir. Aug. 31, 2022) (Newman, Taranto, Chen, JJ.)

In 2018, INVT filed a complaint at the Commission alleging a Section 337 violation by various cell phone companies. INVT asserted that five of its patents were infringed by the 3G and LTE networking standards used by mobile devices (such as cell phones) to communicate with base stations (such as cell phone towers). INVT withdrew two of the asserted patents during the course of the investigation, and the Administrative Law Judge (ALJ) issued an initial determination holding that there was no Section 337 violation because none of the three remaining patents were infringed. The Commission did not disturb that decision on review, and INVT appealed on two of the three asserted patents in June 2020.

Briefing during the appeal was extended several times, and as a result, oral argument did not occur until November 2021. The Federal Circuit then asked for supplemental briefing regarding whether there could be any relief on one of the patents scheduled to expire in March 2022. The Court ultimately issued its decision at the end of August 2022, more than two years after the appeal was filed.

In its decision, the Federal Circuit first held that the appeal was moot as to the expired patent. For the remaining patent, the dispute over infringement resolved to the question of whether the claims required actual operation or could instead be met by mere capability. On that point, the Court reversed the ALJ’s determination that the claims required actual operation. According to the Court, the present-tense claim language used (i.e., “a data obtaining section that demodulates and decodes”) was not significantly different from the sort that is usually interpreted to merely require capability (e.g., “for demodulating and decoding”). But the Court then held that the actual operation of the base stations was relevant to determining whether the accused mobile devices were capable of performing one of the particular claimed functions. The Court thus affirmed the finding of no infringement because INVT had failed to show that the base stations actually operated in a way that would allow the mobile devices to be capable of carrying out the claimed functionality.

Alexander Ott appeared for respondent ZTE at the Commission in this matter.

Check Your Expert Skills and Standing

by Sarah J. Fischer | Sep 8, 2022 | Patents

The US Court of Appeals for the Federal Circuit dismissed a portion of an appeal from the Patent Trial & Appeal Board (Board) regarding obviousness because the patentee did not have standing to challenge the decision regarding one of the claims. The Court also affirmed-in-part because the definition of person of ordinary skill in the art applied by the Board was not unreasonable or unsupported by the evidence. Best Medical International, Inc. v. Elekta Inc., Case Nos. 21-2099; -2100 (Fed. Cir. Aug. 29, 2022) (Hughes, Linn, Stoll, JJ.)

Best Medical International (BMI) owns a patent directed to a method and apparatus for conformal radiation therapy of tumors using a pre-determined radiation dose. The Board instituted two inter partes review (IPR) petitions filed by Varian Medical Systems and Elekta. During the pendency of the IPR proceeding, a parallel ex parte re-examination was ongoing. After institution of the IPRs, the examiner in the re-examination rejected claim 1, which BMI subsequently cancelled “without prejudice or disclaimer.” After BMI cancelled claim 1, the Board issued its final written decision in the IPR proceedings. The Board noted that BMI had cancelled claim 1 during re-examination, but concluded that claim 1 had “not yet been canceled by a final action” because BMI had “not filed a statutory disclaimer of claim 1.” The Board therefore considered the merits of Elekta’s patentability challenge and determined that claim 1 was unpatentable as obvious. The Board issued a split decision as to the other claims, finding one claim patentable and the others unpatentable. BMI appealed.

The Federal Circuit began by analyzing whether BMI had standing to challenge the Board’s invalidation of the now cancelled claim 1. BMI attempted to invoke Munsingwear vacatur, which allows courts to vacate underlying decisions on issues that have become moot during their pendency. As an initial matter, the Court found that the Board had the authority to invalidate the claim because it was not finally cancelled at the time the Board issued its final written decision. Regarding BMI’s vacatur argument, Elekta argued that BMI lacked standing to challenge the decision related to the cancelled claim. BMI countered that it had suffered an injury sufficient to create Article III standing because it believed that collateral estoppel might be applied by the examiner regarding other claims in another patent subject to re-examination. The Court was unpersuaded by this argument, in part because BMI could not cite any case law where collateral estoppel was applied in that fashion. The Court found that Munsingwear vacatur was inappropriate because the mooting event did not happen during the pendency of the appeal—it happened before the appeal was filed. The Court therefore concluded that BMI lacked standing to challenge the Board’s decision regarding the now cancelled claim.

Turning to the other claims the Board found unpatentable, BMI challenged the Board’s finding that a person of ordinary skill in the art must have formal computer programming experience. The Federal Circuit recited the non-exhaustive list of factors used to determine the requisite level of [...]
