Drawing Can Teach Claim Limitations If “Clear on Its Face”

Addressing when a drawing in a prior art reference includes a teaching that is “clear on its face,” the Director of the US Patent & Trademark Office vacated and remanded a Patent Trial & Appeal Board decision denying institution of an inter partes review (IPR) petition. MAHLE Behr Charleston Inc. v. Catalano, IPR2023-00861 (PTAB Decision Review, Apr. 5, 2024) (Vidal, PTO Dir.)

MAHLE Behr filed a petition requesting institution of an IPR, challenging claims of a patent owned by Catalano. The patent is directed to a device known as a sacrificial anode that prevents corrosion in motor vehicle radiators caused by electrolysis. One of the claim terms at issue requires the anode to be “within 10 inches” of another element. MAHLE argued that a figure in a prior art reference anticipated or rendered obvious several challenged claims.

The Board denied the institution after determining that MAHLE did not establish a reasonable likelihood that it would prevail with respect to at least one of the challenged claims. The Board cited the Federal Circuit’s 2000 decision in Hockerson-Halberstadt v. Avia Group International to explain that “[p]atent drawings do not define the precise proportions of the elements and may not be relied on to show particular sizes if the specification is completely silent on the issue.” The Board concluded that the figure relied on by MAHLE did not provide exact dimensions and thus could not be sufficient to render the claims invalid.

MAHLE filed a request for Director Review, which was granted. In its request, MAHLE argued that the Board erred in its application of Federal Circuit case law on the use of patent drawings as prior art teachings. The Director agreed, explaining that “the Board did not adequately address [MAHLE’s] arguments regarding what [the figure in the prior art] clearly shows or would have reasonably suggested to a person of ordinary skill in the art.” Federal Circuit case law established that a claim may be anticipated or rendered obvious by a figure in the prior art if the drawing clearly discloses the claim limitation. If “a person of skill in the art could derive the claimed dimensions from the patent’s disclosure, there is no additional requirement that the specification must explicitly disclose the precise proportions or particular sizes.”

The Director further explained that “the Board did not adequately address MAHLE’s arguments regarding what [the prior art figure] clearly shows or would have reasonably suggested to a person of ordinary skill in the art.” While the prior art figure did not disclose the precise proportions or measured quantity specified in the challenged claims, the figure showed the elements being located as claimed (necessarily within the 10 inches recited). The Director explained that the Board should have considered whether a person of ordinary skill in the art would have understood the figure to disclose the claimed elements being within 10 inches of each other.

The Director vacated the Board’s decision and remanded the petition with instructions to consider both what the prior art figure [...]

Reasonable Royalty Available for Foreign Activities (But Not This Time)

The US Court of Appeals for the Federal Circuit affirmed a district court’s decision to preclude a patent owner from seeking damages based on method claims infringed outside of the United States but confirmed that reasonable royalties are available based on foreign activities. Harris Brumfield v. IBG LLC, Case No. 22-1630 (Fed. Cir. Mar. 27, 2024) (Prost, Taranto, Hughes, JJ.)

Trading Technologies International (TT), whose successor is Harris Brumfield, filed a lawsuit against IBG in 2010 alleging infringement of four patents directed to graphical user interfaces for commodity trading and methods for placing trade orders using those interfaces. During the underlying proceeding, the district court issued several orders. The district court granted IBG’s motion for summary judgment that the claims of two of the patents were invalid. The district court also excluded one of TT’s damages theories concerning foreign activities. Prior to trial, the district court found that two of the patents were invalid as patent ineligible and that the other two patents contained patent eligible subject matter. The district court also excluded one of TT’s damages theories concerning foreign activities.

The case proceeded to trial on the two remaining patents, and the jury found the asserted claims of those two patents infringed. IBG proposed $6.6 million in damages, which corresponds to the total demanded by IBG using IBG’s proposed royalty rate measured against domestic usage, rather than global users. By contrast, TT proposed damages of $962 million, which included all worldwide users of the accused product, regardless of whether they performed the claimed method. The jury agreed with IGB and awarded TT $6.6 million. the district court denied TT’s post-verdict motion for a new trial on damages, a motion in which TT alleged that IBG had misrepresented how it calculated the damages figures it presented to the jury. TT appealed.

Under the Supreme Court’s 2018 decision in WesternGeco v. Ion Geophysical, a patent owner can recover damages in the form of foreign lost profits when infringement is found under 35 U.S.C. § 271(f)(2) of the Patent Act. TT argued that under WesternGeco, it can seek damages in the form of a reasonable royalty based on IBG “making” the accused product in the US, even though the products were used overseas. The Federal Circuit engaged in a detailed description of WesternGeco, concluding that the Court must examine the particular acts alleged to constitute infringement under particular statutory provisions to determine if the allegations focus on domestic conduct. The Court explained that under § 271(a), the making, using, offering to sell and selling provisions are limited to domestic acts. The Court acknowledged that the WesternGeco framework applies to reasonably royalty awards (not just lost profits) and that a reasonable royalty would be the amount a hypothetical infringer would pay to engage in the domestic acts constituting the infringement.

Despite finding that reasonable royalties are permitted under WesternGeco, the Federal Circuit affirmed the district court’s exclusion of TT’s damages theory because TT’s infringement theory about making the accused product [...]

ITC Shines Light on DI: Complainant Can’t Aggregate Investments Across Patents, Prongs

Addressing a determination by its chief administrative law judge (CALJ) finding a violation of § 337, the US International Trade Commission reversed and held that the complainant had not satisfied the economic prong of the domestic industry (DI) requirement by aggregating its investment across multiple asserted patents. Certain Replacement Automotive Lamps (II), Case No. 337-TA-1292 (USITC Mar. 22, 2024).

In late 2021, Hyundai filed a complaint seeking an investigation under 19 U.S.C. § 337 based on alleged infringement of 21 design patents, each covering a different automotive headlamp or taillamp. In response, two of the proposed respondents filed a request seeking early disposition of the economic prong of the domestic industry under the Commission’s 100-day program. Hyundai filed a response opposing the 100-day program request based on the complexity of the issues. The Commission instituted the investigation and denied the 100-day program request, but when setting the procedural schedule, the CALJ scheduled an early evidentiary hearing on the economic prong of the domestic industry pursuant to the Commission’s pilot program for interim initial determinations. Following that initial hearing, the CALJ issued an interim initial determination finding that Hyundai had satisfied the economic prong of the domestic industry requirement. After the full evidentiary hearing, the CALJ issued a final initial determination finding a violation of § 337 by the respondents based on infringement of all asserted patents. The Commission decided to review both the initial and final determinations.

On review, the Commission reversed the finding that the complainant had satisfied the economic prong of the domestic industry requirement. As the Commission explained, where DI products do not have overlapping protection across common asserted patents, a complainant must treat each product as requiring a separate DI showing. The Commission cannot aggregate investments in articles covered by one patent with investments in articles only covered by a different patent. Here, because each DI product practiced only one of the asserted design patents, to satisfy the economic prong Hyundai was required to demonstrate that the investments in each product were independently significant. The Commission also held that investments in plant and equipment (§ 1337(a)(3)(A)) cannot be combined with employment of labor or capital (§ 1337(a)(3)(B)) and concluded that Hyundai had mistakenly aggregated its investments from both prongs.

Commissioner Schmidtlein filed an opinion concurring with the outcome but declining to join the majority opinion based on her view that it went beyond what was necessary to dispose of the investigation.

PTO Stands by Patent Fee Increases

The US Patent & Trademark Office (PTO) issued a notice of rulemaking announcing proposed patent fee increases beginning next year. 89 Fed. Reg. 23226 (April 3, 2024). The proposed increases are generally consistent with the PTO’s May 2023 proposal.

The Notice states that the PTO needs the proposed fee adjustments to provide sufficient revenue to recover costs of patent operations in future years. To that end, the PTO proposes to set or adjust 455 patent fees, including 73 new fees. Complete information about the fee adjustments, including the Notice, is available on the PTO’s website.

The fee increases include higher amounts for routine fees necessary to obtain a patent, including filing, search, examination and issue fees. Excess claim fees will also increase to $200 for each claim over 20 and $600 for each independent claim over three. There will also be an escalating fee structure for terminal disclaimers, ranging from $200 if filed before the first office action to $1,400 if filed after the PTO grants the patent. The fees for filing requests for continued examination (RCE) will now use a tiered fee structure and will increase to $1,500 for the first RCE, $2,500 for the second RCE and $3,600 for the third RCE. Patent Trial & Appeal Board fees will increase by about 25%, and a new fee of $400 will be required for a Request for Director Review of a Board decision.

Written comments on proposed patent fees must be submitted by June 3, 2024, through the Federal eRulemaking Portal.

Faulty Jury Instruction Tampered With Tamper-Proof Trial

The US Court of Appeals for the Federal Circuit affirmed in part, vacated in part and remanded a district court decision after concluding that a jury instruction on the objective indicia of nonobviousness that failed to specify all indicia on which evidence had been received constituted prejudicial legal error. Inline Plastics Corp. v. Lacerta Group, LLC, Case Nos. 22-1954; -2295 (Fed. Cir. Mar. 27, 2024) (Taranto, Chen, Hughes, JJ.)

Inline Plastics owns a patent family pertaining to containers with specific tamper-proof features and methods of producing these containers using thermoformed plastic. The invention is intended to deter unauthorized tampering with products in the containers. These tamper-proof features serve to prevent theft and product loss and maintain consumer confidence in product integrity.

Inline sued Lacerta Group for patent infringement over its tamper-proof technology. The district court made several significant pretrial rulings, including a claim construction order, and granted Inline’s motion for partial summary judgment of infringement on some of the asserted claims. During trial, Inline voluntarily withdrew certain claims, and the jury returned a verdict declaring all remaining claims (even those on which summary judgment had been granted) invalid and not infringed. After trial, Inline sought partial final judgment, which was granted, but also motioned for judgment as a matter of law and a new trial on invalidity. The district court denied Inline’s motions. Both Inline and Lacerta appealed.

Inline argued that it was entitled to judgment as a matter of law of no invalidity and that an error in the jury instructions requires a new trial on invalidity. Lacerta cross-appealed, challenging the denial of attorneys’ fees and the “without prejudice” dismissal of certain patent claims that Inline voluntarily dropped from its asserted-claims list near the end of trial.

The Federal Circuit rejected Inline’s argument for judgment as a matter of law of no invalidity but agreed with Inline that the jury instruction on the objective indicia of nonobviousness constituted prejudicial legal error. The Court determined that the jury could have reasonably found obviousness and rejected Inline’s three arguments against it. First, Inline argued deficiencies in Lacerta’s prior art references and expert testimony, but the Court found these arguments unpersuasive. Second, Inline challenged Lacerta’s evidence of motivation to combine references, but the Court found enough support to prove a motivation to combine. Third, Inline argued that Lacerta’s challenge failed because there was no rebuttal or opinion on objective-indicia evidence. The Court dismissed this argument, explaining that the absence of such testimony did not necessarily discredit the patentee’s evidence on nonobviousness. According to the Court, Inline failed to explain why the jury could not reasonably assign little weight to its objective-indicia evidence, which led the Court to reject Inline’s categorical argument based on the absence of expert testimony from Lacerta’s side.

However, the Federal Circuit agreed with Inline’s argument for a new trial on invalidity. The Court explained that jury instructions must be legally correct and sufficiently comprehensive to address disputed evidence. The Federal Circuit concluded that the district court’s objective-indicia instruction [...]

Who Solved the Problem? Joint Inventors, That’s Who

The US Court of Appeals for the Federal Circuit affirmed a district court’s decision to correct inventorship in a post-issuance inventorship dispute, finding that the alleged joint inventors’ contributions were significant even though they were mostly unclaimed. Tube-Mac Indus., Inc. v. Campbell, Case No. 22-2170 (Fed. Cir. Mar. 15, 2024) (Lourie, Hughes, Stark, JJ.) (nonprecedential).

Steve Campbell was the original sole inventor named on a utility patent application directed to a container for transporting gaseous fluids. Before Campbell filed the patent application, Campbell’s prototypes had a “major problem” with the container’s liner. Campbell enlisted the help of Tube-Mac Industries’ Gary Mackay and Dan Hewson to solve the problem. Campbell, Mackay and Hewson exchanged plans regarding the problem over the course of several months. Campbell’s patent issued, naming himself as the sole inventor. Mackay, Hewson and Tube-Mac filed suit seeking to be named as co-inventors. The district court agreed and ordered correction of the patent under 35 U.S.C. § 256. Campbell appealed.

A court may order a correction of inventorship when it determines that an inventor has been erroneously omitted from a patent. In any inventorship challenge, the inventors listed in an issued patent are presumed to be the correct inventor(s). Thus, a party challenging inventorship must prove incorrect inventorship by clear and convincing evidence. A joint inventor must contribute significantly to the invention’s conception or reduction to practice when that contribution is measured against the scope of the full invention.

The Federal Circuit found that prior to the involvement of Mackay and Hewson, Campbell did not have a viable invention that could be reduced to practice without extensive experimentation. The Court also found that Mackay’s and Hewson’s contributions solved the problem that precluded the prototype from being successful, even though their contributions were “mostly unclaimed.” The Court noted, however, that their contributions were included in the application’s figures, specifications and dependent claims. Accordingly, the Court found that Mackay and Hewson contributed significantly to the conception of the invention and should be included as co-inventors.

The Federal Circuit also dismissed Campbell’s arguments that the district court did not properly construe the claims to determine their scope and erred by misidentifying the subject matter of the claims.

What Use Does § 271(e)(1) Safe Harbor “Solely” Protect?

The US Court of Appeals for the Federal Circuit affirmed that the 35 U.S.C. § 271(e)(1) safe harbor protecting certain infringing acts undertaken for regulatory approval applied to an alleged infringer’s importation of transcatheter heart systems while attending a trade conference, finding the importation reasonably related to submitting information to the US Food & Drug Administration (FDA) for medical device approval. Edwards Lifesciences Corp. v. Meril Life Sciences Pvt. Ltd., Case No. 22-1877 (Fed. Cir. Mar. 25, 2024) (Stoll, Cunningham, JJ.) (Lourie, J., dissenting).

The fact pattern in this case is unusual. Meril, a manufacturer of a transcatheter heart system approved for sale in Europe but not in the United States, brought two demonstration samples to San Francisco with lawyer-generated instructions that the samples could not be used, sold or offered for sale in the US. Meril presented at a trade booth during a cardiovascular medical device conference. It was undisputed that the samples never left a bag that was first kept at a hotel and later brought to the conference and placed in a storage room.

Edwards Lifesciences nevertheless sued for infringement based on importation. The district court found that Meril’s importation was reasonably related to its attempts to secure regulatory approval because they were for the purposes of recruiting investigators for a clinical trial Meril had made initial efforts to commence (as required to market this type of device in the US). Accordingly, the district court granted summary judgment of noninfringement on grounds that the safe harbor under § 271(e)(1) applied. Edwards appealed.

Edwards argued that the district court erred by not finding a genuine material dispute of fact relating to Meril’s subjective intent (i.e., whether, notwithstanding some evidence, Meril actually intended the importation to relate to FDA approval). Edwards also challenged whether the importation was solely related to FDA approval and argued that the non-use of the devices to recruit investigators rendered the safe harbor inapplicable.

The Federal Circuit rejected all three challenges. Canvassing the Federal Circuit’s decades of prior case law, the Court concluded that a putative infringer’s intent is irrelevant when determining whether the safe harbor applies. Thus, even if Edwards were correct in challenging Meril’s intent, there would still be no material factual dispute. On the issue of whether the importation activity was solely related to FDA approval, the Court, discussing the use of “solely” in terms of the safe harbor provision, reiterated prior cases’ determination that the uses need not be solely related to FDA approval, but rather, that the only uses that would be protected were those within the safe harbor. Finally, the Court again deemed the non-use of the devices irrelevant, as nothing in the statute required actual use.

Judge Lourie dissented, not because he necessarily viewed the district court’s or the majority’s application as squarely incorrect under existing precedent, but because he believed that existing precedent did not expressly give proper weight to the statute’s use of the word “solely.” Applying a plain text analysis, Judge Lourie argued that the safe harbor [...]

Mandamus Denied but Jurisdictional Door Left Open a Crack

The US Court of Appeals for the Federal Circuit denied a patent owner’s writ of mandamus seeking to prevent a defendant from amending its answer to add an affirmative licensing defense, but also noted that the defense was added only after the district court found that there were no remaining claims. In re VLSI Technology LLC, Case No. 24-116 (Fed. Cir. Mar. 18, 2024) (Moore, Taranto, Chen, JJ.)

VLSI asserted four patents against Intel in the Northern District of California. In December 2023, the district court granted summary judgment that two of the patents were not infringed and denied summary judgment of noninfringement on the remaining two patents. The parties additionally submitted cross motions for summary judgment on a licensing defense that turned on a forum selection clause, but the court denied both motions. To deprive the court of jurisdiction, VLSI granted Intel a covenant not to sue for infringement of the remaining two patents in the case. Two days later, Intel moved to amend its answer to add a counterclaim for a declaratory judgment that Intel was licensed to VLSI’s entire patent portfolio. The district court granted Intel’s motion, and VLSI filed a mandamus petition to block Intel’s amendment.

The Federal Circuit denied VLSI’s petition for two primary reasons. First, the Court determined that VLSI had not shown that it had no other available means of obtaining relief. The district court expressly invited the parties to brief issues pertaining to Intel’s licensing defense in subsequent briefing, and VLSI had since filed a motion to dismiss pertaining to this very issue. The Court also noted that VLSI could raise this issue on appeal after a final judgment. Second, the Court determined that VLSI failed to show that the district court abused its discretion in allowing Intel to amend its answer, finding that Intel acted diligently in seeking to amend its answer and that VLSI had long since known about the potential defense.

With respect to the substantive issue of whether the district court had subject matter jurisdiction, the Federal Circuit declined to offer an opinion at this stage. Nevertheless, in an apparent message to the court below, the final sentence of the Court’s opinion reads, “[w]e only note that Intel’s motion to amend its answer was filed after the court determined there were no remaining claims, such that no case or controversy remained before the court.”

Is Evidence of All Claimed Elements in Prior Art Enough? Not Without Motivation to Combine

The US Court of Appeals for the Federal Circuit reversed a Patent Trial & Appeal Board obviousness decision, finding that disclosure in the prior art of all recited claim elements across multiple references, without more, does not establish obviousness unless there is evidence of a motivation to combine. Virtek Vision Int’l ULC v. Assembly Guidance Systems, Inc., Case No. 22-1998 (Fed. Cir. Mar. 27, 2024) (Moore, C.J.; Hughes, Stark, JJ.)

Virtek holds a patent that discloses “an improved method for aligning a laser projector with respect to a work surface.” Lasers are used to “project a template image onto a work surface to direct manufacturing processes.” The patent discloses a two-step process that improves efficiency over the prior art.

Aligned Vision petitioned for inter partes review (IPR), challenging all of the patent’s claims. Aligned Vision asserted four combinations of prior art references over which it contended the claims were obvious. In its Final Written Decision, the Board found that some of the claims were unpatentable as obvious, but others were not.

The Board determined that certain claims, which depended from the independent claim, would have been obvious over two combinations of references: Keitler and Briggs, and Briggs and Bridges. In pertinent part, the independent claim recites “identifying a pattern of the reflective targets on the work surface in a three dimensional coordinate system.” Save for the 3D claim element, all the other claim elements were disclosed in Bridges and Keitler. The Board found that a skilled artisan would have been motivated to use the 3D coordinate system disclosed in Briggs instead of the angular direction systems in Keitler or Bridges. The Board reasoned that this combination would have been obvious to try because Briggs disclosed both 3D coordinates and angular directions.

With respect to the direct appeal, the Federal Circuit found that the Board erred as a matter of law regarding motivation to combine. “It does not suffice to meet the motivation to combine requirement to recognize that two alternative arrangements such as an angular direction system using a single camera and a 3D coordinate system using two cameras were both known in the art.” Rather, the patent challenger must show that a skilled artisan would swap the element in one reference for an element in another reference. “The mere fact that these possible arrangements existed in the prior art does not provide a reason that a skilled artisan would have substituted the one-camera angular direction system in Keitler and Bridges with the two-camera 3D coordinate system disclosed in Briggs.”

Here, the patent challenger presented no argument in the IPR petition regarding why a skilled artisan would make this substitution, other than that the two different coordinate systems were “known to be used.” Specifically, Briggs made no mention of any benefits the 3D system might provide over the angular system. Aligned Vision’s expert testified multiple times that he could not provide a reason to combine the references, and Aligned Vision presented no evidence that “there are a finite number of [...]

Same Product in Different Packaging May Constitute Separate Market for Antitrust Purposes

Addressing an issue of first impression, the US Court of Appeals for the Second Circuit concluded that two medications that contain the same ingredients but are packaged in different forms constitute separate markets for purposes of assessing antitrust violations. Regeneron Pharm., Inc. v. Novartis Pharma AG, Case No. 22-0427 (2d Cir. Mar. 18, 2024) (Parker, Lee, Merriam, JJ.)

Regeneron sued Novartis in the US District Court for the Southern District of New York alleging antitrust violations under the Sherman Act and New York state law claims. The specific products at issue were prescription medications used to treat the overproduction of vascular endothelial growth factor (VEGF). VEGF is a naturally occurring protein but, if overproduced, can lead to eye disorders, including permanent blindness. Both Regeneron and Novartis produce medication to combat overproduction of VEGF. The first form of anti-VEGF medications developed was packaged into vials and administered in a two-step process where a physician draws the product into a syringe then injects the product into the patient’s eye. However, a newer version of anti-VEGF drugs come in a prefilled syringe (PFS) designed to be administered in one step. The PFS packaging carries a significantly lower risk of complications and infections. PFSs have become the “preferred way [to] administer [] anti-VEGF medications.” Novartis moved to dismiss the complaint under Fed. R. Civ. P. 12(b)(6). After the district court granted the motion, Regeneron appealed.

The district court reasoned that original and newer products competed in the same market because they were the exact same medication, just sold in different forms. The Second Circuit disagreed. PFSs reduce the likelihood of complications and have become the preferred form of administration for treatment of VEGF overproduction over vials. The Second Circuit concluded that the district court improperly focused its analysis on whether the two products were “functional substitutes” and not on whether they were “economic substitutes.” The Second Circuit concluded that the district court had applied the improper standard for the relevant market and should instead consider whether the two drugs are economic substitutes. That is to say, the district court should look to whether the different packaging for the VEGF treatments are reasonably interchangeable by consumers. Regeneron alleged they are not due to PFSs’ preferred status among physicians (although PFSs are more costly than vials).

As to the state law claims, the district court dismissed Regeneron’s tortious interference claims as untimely. On appeal, Regeneron argued that Novartis should be equitably estopped from invoking the statute of limitation because the defendants “took steps to prevent Regeneron from learning of Novartis’s tortious interference until after the statute of limitation period had expired.” The Second Circuit found that Novartis concealed a co-inventor’s role in the procurement of a patent, which Regeneron only found out about during subsequent patent litigation, and that such concealment was in violation of a contract. Thus, the Court “conclude[d] that [Regeneron’s] allegations were sufficient to permit Regeneron to invoke equitable estoppel.” Additionally, the complaint “plausibly alleged a claim for tortious interference with contract.”
