PTO Proposes Deferred Responses for Subject Matter Eligibility Rejections

In a January 6, 2022, Federal Register notice, the US Patent and Trademark Office (PTO) announced its intention to implement a pilot program to evaluate the effects of permitting applicants to defer responding to subject matter eligibility (SME) rejections in certain patent applications. Under this pilot program, applicants may receive invitations to participate if their applications meet the program’s criteria, including a criterion that the claims in the application necessitate rejections on SME and other patentability-related grounds. An applicant who accepts the invitation to participate in this pilot program must still file a reply addressing all the rejections except SME rejections in every office action mailed in the application but is permitted to defer responding to SME rejections until the earlier of final disposition of the application or the withdrawal or obviation of all other outstanding rejections.

Invitations to participate in the Deferred Subject Matter Eligibility Response pilot program will be mailed during the period between February 1, 2022, and July 30, 2022. The PTO may extend, modify or terminate the pilot program depending on the workload and resources necessary to administer the program, feedback from the public and the program’s effectiveness.

Because satisfaction of non-SME conditions for patentability (e.g., novelty, nonobviousness, adequacy of disclosure and definiteness) may resolve SME issues as well, the pilot program may result in improved examination efficiency and increased patent quality.

An examiner may invite a prospective applicant to participate in the pilot program by including a form paragraph in the first office action on the merits. An applicant receiving an invitation to participate in the pilot program may elect to accept or decline the invitation. If an applicant wishes to participate in the program, they must file a properly completed request form PTO/SB/456 concurrently with a timely response to the first office action on the merits. The request form must be submitted via the PTO’s patent electronic filing systems.

The limited waiver permits the applicant to defer addressing the SME rejections until the earlier of final disposition of the participating application or the withdrawal or obviation of all other outstanding rejections. A final disposition is the earliest of the following:

  • Mailing of a notice of allowance
  • Mailing of a final office action
  • Filing of a notice of appeal
  • Filing of a request for continued examination
  • Abandonment of the application.

Applicants must address the SME rejections in a response to a final rejection or the filing of a request for continued examination.

The public is invited to submit comments, which must be received by March 7, 2022, to ensure consideration.

Improper Claim Construction Requires Partial Remand of Obviousness Determination

The US Court of Appeals for the Federal Circuit issued decisions in two separate inter partes reviews (IPRs), one involving a patent related to radio frequency communication systems and the other involving a patent related to multi-processor systems. Intel Corporation v. Qualcomm Incorporated, Case No. 20-1664 (Fed. Cir. Dec. 28, 2021) (Prost, Taranto, Hughes, JJ.); Intel Corporation v. Qualcomm Incorporated, Case Nos. 20-1828, -1867 (Fed. Cir. Dec. 28, 2021) (Prost, Taranto, Hughes, JJ). Based on issues of claim construction and obviousness, the Court affirmed in part and vacated in part the Patent Trial and Appeal Board’s (Board) decision in the radio frequency communication systems patent IPR and vacated the Board’s decision in the multi-processor systems patent IPR.

Radio Frequency Communication System Patent IPR (1664)

In the IPR related to the radio frequency communication systems patent, Intel proposed that the claim term “radio frequency input signal” should take its ordinary meaning of an input signal having a radio frequency. Qualcomm argued that a person of skill in the art reading the patent would understand the phrase to reference the radio frequency signal that is received before down-conversion, and thus proposed that the term should mean “a signal centered at a carrier frequency at which the signal was transmitted/received.” The Board agreed with Qualcomm based on the intrinsic evidence.

Intel argued before the Board that certain claims of the radio frequency communication systems patent would have been obvious in light of the Der reference and the Valla reference. Qualcomm argued that a skilled artisan would not have been motivated to combine Der and Valla, because Der’s transistor would defeat the intended purpose of Valla’s amplifier. The Board agreed with Qualcomm. Qualcomm also submitted substitute claims. The Board accepted the substitute claims after finding that a skilled artisan would have lacked reason to combine Der and the Burgener reference to achieve the substitute claims. Intel appealed.

The Federal Circuit first addressed the threshold question of whether it had jurisdiction since no lawsuit had been filed against Intel. Despite the absence of any lawsuit against Intel itself, the Court found that Intel had standing because it had engaged in acts that previously resulted in assertion of the patent against one of Intel’s customers. Because Intel continues to sell the relevant products to that customer and others, it must address the risk of an infringement suit by Qualcomm. Qualcomm also refused to offer a covenant not to sue or stipulate that it would not reassert its prior infringement allegations involving the Intel products. The Court found that this refusal made Intel’s risk more than “mere conjecture or hypothesis.” Therefore, the Court found that Intel had standing to pursue the appeal.

Turning to the merits, the Federal Circuit affirmed the Board’s construction of “radio frequency input signal.” The Court explained that while both parties’ proposed constructions had appeal when considered in a vacuum, the proper inquiry required analysis of the surrounding claim language and specification. The Court found that linguistic clues in the claims suggested that [...]

Change the Look of the Room: Appeal Transferred to Federal Circuit

The US Court of Appeals for the Second Circuit transferred an appeal of a preliminary injunction enjoining alleged copyright and trademark infringement to the US Court of Appeals for the Federal Circuit because the operative complaint included six counts of patent infringement and thus arose under patent law. Hudson Furniture, Inc. et al. v. Lighting Design Wholesalers Inc., Case No. 20-3299 (2d Cir. Dec. 21, 2021) (Livingston, CJ; Kearse, Lee, JJ.) (per curiam).

Hudson filed a complaint against Lighting Design alleging patent, trademark and copyright infringement. The district court granted Hudson’s preliminary injunction and enjoined Lighting Design from alleged infringement of Hudson’s copyrights and trademarks. The district court also denied Lighting Design’s motion to dismiss for lack of personal jurisdiction and its motion for reconsideration permitting alternative service of process. Lighting Design appealed the rulings to the Second Circuit.

Hudson asked the Second Circuit to dismiss the appeal, arguing that the appeal arose from a complaint involving patent law claims and thus fell under the exclusive jurisdiction of the Federal Circuit. Under 28 U.S.C. §§ 1292 and 1295, the Federal Circuit has exclusive jurisdiction over interlocutory appeals involving any action that arises under any act of US Congress relating to patents. An action arises under patent law when a well-pleaded complaint establishes that (1) federal law creates the cause of action or (2) the plaintiff’s right to relief necessarily depends on resolution of a substantial question of federal patent law.

The Second Circuit agreed that exclusive jurisdiction rested with the Federal Circuit, explaining that the operative complaint included six counts of patent infringement, and the appeal concerned the district court’s ruling on a motion for injunctive relief involving patent law and non-patent law claims. The Court rejected Lighting Design’s argument that patent law did not constitute a substantial part of the overall success of the case since Hudson failed to secure preliminary injunctive related to the patent law claims. The Court explained that Lighting Design’s argument focused on only the second basis for Federal Circuit jurisdiction (whether the right to relief depends on a “substantial question” related to patent law). The Court found that even if it accepted Lighting Design’s argument, the fact that federal patent law created the cause of action was sufficient to establish Federal Circuit jurisdiction under the first basis of jurisdiction. While the Second Circuit agreed with Hudson, it declined to dismiss the appeal and instead opted to transfer the appeal to the Federal Circuit because the original appeal was timely filed in good faith and transferring the appeal was in the interest of justice.

Can’t Overturn Jury Verdicts Based on Reasonable Inferences, but Broad Injunction Is Nonstarter Even for Willfully Misappropriated Trade Secrets

In a rare appellate trade secret opinion, the US Court of Appeals for the Eleventh Circuit affirmed a district court’s denial of a defendant’s request for a new trial on liability and its refusal of the plaintiff’s requested injunction. It also reversed in part the district court’s denial of judgment as a matter of law (JMOL) on damages for clear error because the plaintiff failed to deduct marginal costs when calculating lost profits. Financial Information Technologies v. iControl Systems, Case No. 20-13368 (11th Cir. Dec. 22, 2021) (Jordan, Newsom, JJ., and Burke, Distr J.).

Competitors Financial Information Technologies (Fintech) and iControl Systems both sell software that processes alcohol sales invoices within 24 hours. Fintech was a lone operator for several years until iControl started servicing the alcohol industry and began selling a very similar product at a lower price point. After Fintech lost its vice president of operations (who was very involved in designing Fintech’s software), a sales representative and several customers to iControl, Fintech filed suit alleging misappropriation of trade secrets. The jury ruled in Fintech’s favor and awarded compensatory and punitive damages. iControl sought a new trial on liability, contending that Fintech’s alleged trade secrets were readily ascertainable and not “secret,” and JMOL on damages since Fintech hadn’t proved lost profits because it hadn’t deducted fixed and marginal costs from its lost revenue calculations. Fintech sought a permanent injunction prohibiting iControl from using either company’s software. The district court denied all three motions, and both parties appealed.

As to the jury verdict, the Eleventh Circuit noted that jury liability findings are generally difficult to overturn, and that the verdict was general and nonspecific regarding which of the seven alleged trade secrets iControl had misappropriated, so Fintech only needed to show evidence under the Florida Uniform Trade Secrets Act (FUTSA) of misappropriation as to one. iControl also did not move for JMOL on liability, and therefore, under the abuse-of-discretion standard of review, the Court could only overturn if “there is an absolute absence of evidence to support the verdict.” However, the Court found that Fintech and its witness presented sufficient evidence at trial to permit a reasonable jury to find that Fintech possessed at least one of the seven alleged trade secrets and that it was misappropriated. The evidence included emails indicating that its former vice president helped iControl discover Fintech’s internal processes to aid software developments, assisted iControl’s chief technology officer in troubleshooting issues in a manner similar to Fintech, shared screenshots of Fintech’s user portal and prompted customers to switch to iControl.

Similarly, the Eleventh Circuit found that the jury reasonably could have inferred from the evidence that iControl schemed to hire Fintech employees to misappropriate Fintech’s software features—an act that demonstrated willfulness.

After assessing the meanings of fixed and marginal costs and the properly fact-intensive revenue and profits figures of the businesses, the Eleventh Circuit agreed that the jury was not required to deduct Fintech’s fixed costs from its revenues to arrive at a proper “actual [...]

Copyright Office Solicits Comments on Deferred Examination Option

The US Copyright Office announced a public study to evaluate the merits of providing an option to defer examination of copyright registration materials until a later request by the applicant. Deferred Registration Examination Study: Notice and Request for Public Comment, 86 Fed. Reg. 70540 (Dec. 10, 2021). To aid in the effort, the Copyright Office is soliciting public comments, which are due by January 24, 2022.

Copyright protection automatically attaches to an original work of authorship as soon as it’s created and fixed in tangible form. Although registration is optional, the US Copyright Act provides significant incentives to encourage registration, which only occurs after the Copyright Office examines the work and determines that it is copyrightable. This process can often take many months. In 2019, the Supreme Court of the United States held that a lawsuit for copyright infringement can be brought only after the Copyright Office registers the copyright. Fourth Estate v. Wall-Street.com, Case No. 17-571 (US March 4, 2019) (Ginsburg, Justice).

There is currently no option to delay or defer examination of submitted application materials. In an effort to modernize its technological infrastructure, the Copyright Office has previously solicited public input concerning the registration process. Respondents have submitted various proposals involving a deferred examination proceeding, some of which included:

  • Allowing applicants to submit application materials at a discounted fee
  • Delaying examination but still intaking information about the work into the public catalog
  • Allowing formal examination to determine whether the work should be registered at a later time for an additional fee
  • If the work is registered, attaching statutory benefits with an effective date of when the original materials were received.

Commenters have indicated that benefits of permitting deferred examination include more registrations, more timely registrations, expansion of the public record, improved efficiency by removal of the examination step, decreased processing times, lower expenses and more deposits available for the Library of Congress’s collections.

In May 2021, Senator Thom Tillis, the ranking member of the Senate Judiciary Subcommittee on Intellectual Property, sent a letter to the Copyright Office requesting a study on the feasibility, benefits and costs of creating a deferred examination option for an application, including whether an applicant can obtain an effective date of registration upon submission and deposit while choosing to defer examination until a later time. He also asked the Copyright Office to consider whether statutory changes might be necessary to enable such an option.

In order to assess the viability of including a deferred examination option, the Copyright Office is inviting written comments on various subjects, including:

  • The deficiencies in the current registration process
  • The potential benefits and drawbacks of a deferred examination option
  • The possible legal or regulatory framework for the option
  • The impact of such an option on the Copyright Office, the Library and the ability to bring a lawsuit based on Fourth Estate
  • Whether the same goals that deferred examination is meant to achieve could be accomplished through alternative [...]

Rounding Error: Intrinsic Evidence Informs Plain and Ordinary Meaning

Vacating a stipulated infringement judgment based on an incorrect claim construction, the US Court of Appeals for the Federal Circuit explained that it is improper to isolate claim language from the intrinsic evidence when determining the plain and ordinary meaning of a disputed term. AstraZeneca AB v. Mylan Pharms. Inc., Case No. 21-1729 (Fed. Cir. Dec. 8, 2021) (Stoll, J.) (Taranto, J., dissenting).

AstraZeneca sued Mylan Pharmaceuticals for infringement of three patents listed in the US Food and Drug Administration’s (FDA) orange book covering the Symbicort® pressurized metered-dose inhaler for the treatment of asthma and COPD. 3M submitted an abbreviated new drug application (ANDA) to the FDA to manufacture and sell a generic version of the Symbicort® inhaler and certain interests to the ANDA were later transferred to Mylan. After receiving a Paragraph IV letter from Mylan, AstraZeneca filed an infringement suit.

Shortly before trial, the district court held a claim construction hearing to determine the meaning of “0.001%,” the claimed concentration of PVP (one of the active ingredients). The district court construed the term based on its “plain and ordinary meaning, that is, expressed with one significant digit.” Based on this definition, Mylan stipulated to infringement and the district court entered judgment. The district court held a bench trial on invalidity, ultimately determining that Mylan did not prove that the claims were invalid as obvious. Mylan appealed the stipulated judgment stemming from the claim construction determination and the judgment of no invalidity.

First, Mylan challenged the district court’s claim construction of “0.001%.” AstraZeneca argued that the district court improperly construed the term to encompass a range from 0.0005% to 0.0014%. Mylan contended that, in view of the specification and the prosecution history, the term was to be defined precisely at 0.001% with only “minor variations” allowed. The Federal Circuit agreed, finding that Mylan’s proposed construction was more properly aligned with the patent’s description as further informed by the prosecution history.

The Federal Circuit stated that the proper construction of 0.001% only allowed minor variations from 0.00095% to 0.00104%. There was no dispute that the term 0.001% would ordinarily encompass the range of 0.0005% to 0.0014%. AstraZeneca argued that this “ordinary meaning” would control absent lexicography or disclaimer. The Court disagreed, finding that it would improperly isolate the term from the claim language, specification and patent prosecution history. The Court explained that the “ordinary meaning” is not the ordinary meaning in the abstract but is instead the “meaning to the ordinary artisan after reading the entire patent,” and therefore the claims must be read in view of both the written description and the prosecution history. The Court’s rationale for narrower construction was based on the intrinsic record reflecting that the written description and prosecution history showed that very minor differences in PVP concentration would impact stability.

The Federal Circuit found that the written description explained that stability was one of the most important factors and that even very minor differences in PVP concentration could impact stability. The written description also [...]

Shots Fired: Challenger Must Have Requisite Standing Before Appealing Unfavorable IPR Decisions

The US Court of Appeals for the Federal Circuit found, in the context of an appeal from an inter partes review (IPR) decision, that the appellant had Article III standing and affirmed a Patent Trial & Appeal Board (Board) decision, holding the challenged claims unpatentable as obvious. ModernaTX, Inc. v. Arbutus Biopharma Corporation, Case No. 20-2329 (Fed. Cir. Dec 2, 2021) (Lourie, J.)

Arbutus owns a patent pertaining to “stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (such as one or more interfering RNA), methods of making the SNALP, and methods of delivering and/or administering the SNALP.” Moderna petitioned for IPR of the patent, asserting three grounds:

  1. Moderna alleged that all claims of the challenged patent would have been anticipated and/or obvious in light of International Pat. Publ. WO 2005/007196 (‘196 PCT) or US Pat. Publ. 2006/0134189 (‘189 publication).
  2. Moderna alleged that all claims of the challenged patent would have been obvious over a combination of the ‘196 PCT, the ‘189 publication, Lin and Ahmad.
  3. Moderna alleged that all claims of the challenged patent were anticipated by US Pat. Publ. 2006/0240554 (‘554 publication), and alternatively that the claims would have been obvious over the ‘554 publication.

The Board rejected each of Moderna’s allegations, finding that the claims were not unpatentable as obvious. Moderna appealed.

Before addressing Moderna’s appeal on its merits, the Federal Circuit addressed whether Moderna had proper standing to challenge the Board’s decision. The Court stated that well-established precedent dictates that an appellant seeking review of a Board decision in an IPR must have suffered an injury in fact that is fairly traceable to the challenged conduct of the appellee and is likely to be redressed by a favorable judicial decision. The Court underscored that under IPR statute, there is no standing requirement for petitioners to request institution of IPR by the Board, meaning that a requester need not have a concrete stake in the outcome. Additionally, where the statue itself grants judicial review (such as in the case of an IPR), standing criteria of immediacy and redressability may be “relaxed.” Nonetheless, the Court explained that a party’s participation in the underlying IPR alone does not confer standing on that party to appeal the Board decision before an Article III court such as the Federal Circuit. The party seeking review (in this case Moderna) must show that it possesses requisite injury for standing to appeal.

Moderna asserted that substantial risk existed that Arbutus would bring an infringement suit against Moderna based on Moderna’s COVID-19 vaccine if the challenged patent was to remain valid. In support, Moderna submitted a declaration from its senior vice president and deputy general counsel that Moderna was working to harness proprietary mRNA technology and planned on releasing and applying for emergency use authorization for a COVID-19 vaccine in December 2020. The declaration also described how Arbutus’s conduct created a substantial risk that it would bring subsequent infringement action against Moderna. An example of such conduct was a series of public statements [...]

Post-AIA Patents Are Not Shielded from Interferences

Addressing the applicability of interference proceedings to patent applications filed after the Leahy-Smith America Invents Act (AIA) was enacted, the Patent Trial & Appeal Board (Board) found it proper to declare an interference between a patent application with a priority date before March 16, 2013, the AIA implementation date, and a patent with a priority date after March 16, 2013. SNIPR Technologies Limited v. The Rockefeller University, Pat. Interf. No. 106,123 (DK) (PTAB Nov. 19, 2021) (Katz, APJ).

The AIA switched the US patent system from a “first to invent” to a “first inventor to file” system. In line with this change, the AIA eliminated the patentability requirement under 35 U.S.C. § 102(g), regarding whether another inventor made the invention first, and the interference proceeding under 35 U.S.C. §135 for determining who invented the claimed invention first. Section 3(n)(2) of the AIA provides a timing provision relating to this change. Under this section, the interference proceeding “shall apply to each claim of an application for patent, and any patent issued thereon, for which the amendments made by this section also apply, if such application or patent contains or contained at any time, a claim [having a priority date before March 16, 2013].”

The US Patent & Trademark Office (PTO) declared an interference between several patents owned by SNIPR and a pending application to The Rockefeller University. The claims involved were drawn to a method of killing or modifying specific bacteria in a mixed population of bacteria with different species using the CRISPR-mediated gene editing technology. The Rockefeller application asserted a priority date of February 7, 2013 (i.e., pre-AIA), while the SNIPR patents asserted the priority date of May 3, 2016 (i.e., post-AIA). SNIPR argued that the interference proceeding was improper since all involved patents were filed after the AIA was enacted.

The Board rejected SNIPR’s argument, explaining that Section 3(n)(2) provides for continuation of interference under certain circumstances. The Board noted that the patentability requirement under 35 U.S.C. §102(g) and interference still apply to each claim having a priority date before March 16, 2013, such as the claims of Rockefeller’s involved application. Accordingly, when the Rockefeller claims would otherwise be allowable, except for the existence of an interference with other claims such as SNIPR’s claims, Section 3(n)(2) necessarily calls for an interference proceeding between the Rockefeller application and the SNIPR patents. Otherwise, the PTO would not be able to determine whether Rockefeller was entitled to a patent under 35 U.S.C. §102(g).

The Board further reasoned that, instead of ending all interferences at the implementation of the AIA, US Congress enacted Section 3(n)(2) to continue the interference proceeding as applicable to certain cases after AIA. Congress also did not explicitly require that cases involved in interferences must all have priority dates before March 16, 2013. Therefore, the Board found that Congress contemplated interferences between pre-AIA and post-AIA applications and patents. Accordingly, the Board ruled in Rockefeller’s favor, finding it was the first to invent the claimed technology.

Obvious to Try Requires Reasonable Expectation of Success Tethered to Claimed Invention

Addressing obviousness in the context of method of treatment claims using particular drug dosages, the US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) final written decision holding that Teva failed to prove obviousness because it failed to show a reasonable expectation of success. Teva Pharms., LLC v. Corcept Therapeutics, Inc., Case No. 21-1360 (Fed. Cir. Dec. 7, 2021) (Moore, C.J.)

Corcept filed a New Drug Application (NDA) for Korlym, a 300 mg mifepristone tablet administered to certain patients with Cushing’s syndrome. The US Food and Drug Administration (FDA) approved Corcept’s application but required a drug-drug interaction clinical trial to determine drug safety when co-administered with strong CYP3A inhibitors such as ketoconazole (Lee memorandum). Corcept conducted the drug-drug interaction study and received a patent relating to methods of treating Cushing’s syndrome by co-administering mifepristone and a strong CYP3A inhibitor based on the data from the Lee memorandum.

Teva sought post-grant review of the patent after Corcept asserted it against Teva in district court. Teva argued that the patent would have been obvious in view of Korlym’s label and the Lee memorandum and submitted a supporting expert declaration. The Board held that Teva failed to prove that a skilled artisan would have had a reasonable expectation of success for safe co-administration of more than 300 mg of mifepristone with a strong CYP3A inhibitor, and thus failed to prove that the patent was obvious. Teva appealed, arguing that the Board erroneously required precise predictability rather than reasonable expectation of success in achieving the claimed invention, and that the Board did not apply Federal Circuit prior art range precedents.

The Federal Circuit affirmed the Board’s decision. Turning first to reasonable expectation of success, the Court explained that the analysis must be tied to the scope of the claimed invention. Because the patent required safe administration of a specific amount of mifepristone, the Board did not err in requiring Teva to show a reasonable expectation of success for a specific mifepristone dosage. Applying this correct standard, the Court found that the evidence supported that a skilled artisan would have had no expectation as to whether co-administering dosages of mifepristone above the 300 mg/day threshold set forth in the Korlym label would be successful. The Federal Circuit also agreed with the Board that Teva’s expert testimony supported a finding of no expectation of success in achieving the claimed invention based on inconsistent testimony before and after institution.

Turning next to the applicability of Federal Circuit prior art range precedents, the Federal Circuit found that Teva had failed to prove that the general working conditions disclosed in the prior art encompassed the claimed invention. Substantial evidence supported the Board’s finding that there was no overlap in ranges because the prior art (Korlym label and industry publications) capped the range of co-administration dosages at 300 mg/day. The Court also noted that Teva’s reliance on mifepristone monotherapy dosages to create an overlap in the claimed ranges failed because the patent claims [...]

PTO Will Transition to Electronic Issuance of Patents and Trademarks

The US Patent & Trademark Office (PTO) announced on December 10, 2021, that it intends to transition to electronic issuance of patents and trademarks in 2022. Under the current rule (37 C.F.R § 1.315), the PTO must deliver or mail a patent “upon issuance to the correspondence address of record.” The PTO will soon issue a notice of proposed rulemaking to seek public feedback on revising the rules of practice to issue patents electronically. Under the proposed changes, the PTO would no longer mail patents to the applicant. Instead, the PTO would issue patents electronically via the Patent Center and Patent Application Image Retrieval, from which the patents could be downloaded and printed.

While no changes to the trademark rules are necessary, the PTO will also issue a public request for comments on replacing paper registration certificates with digital versions.

The PTO believes that electronic issuance will reduce the time it takes for a patent or trademark to issue by about two weeks.

Once the transition is complete, applicants can still receive a paper copy of the issued patents and trademark registration certificates with an embossed gold seal and the director’s signature (i.e., a ribbon certificate) for a fee of $25 per copy.
