Means-Plus-Function Claims in Patent Eligibility and Infringement Analyses

Patent, , , , , , , , , ,

by Dennis Crouch

Means-plus-function claims have generally been disfavored because of the tendency of courts to  either (1) narrowly construe their scope when corresponding structure is detailed in the specification or (2) render them invalid as indefinite when the specification lacks sufficient corresponding structure. If Impact Engine’s petition is well received, there is a good chance that this historically popular claim style will see a revival. 

The Federal Circuit’s recent decision in Impact Engine v. Google has again raised the issue of over the proper treatment of MPF, this time regarding patent eligibility and infringement analyses. Appeal No. 22-2291  (Fed. Cir. July 3, 2024).  I had skipped a write-up of the non-precedential decision, but now Impact Engine has petitioned for en banc review, arguing that (more…)

Federal Circuit Narrows AIA Grace Period: Public Disclosure Must Make Invention ‘Reasonably Available’

Patent, , , , , , , ,

by Dennis Crouch

The Federal Circuit’s new decision in Sanho v. Kaijet highlights the narrowness of the pre-filing grace period (safe harbor) provision under the America Invents Act (AIA) and serves as a reminder that there are a number of patents that would have been valid under the pre-AIA patent system may no longer be valid under the current law. Sanho Corp. v. Kaijet Technology International Limited, Inc., No. 2023-1336 (Fed. Cir. July 31, 2024).

The basic holding is that the 102(a)(2)/(b)(2) safe harbor triggered by an inventor’s pre-filing “public disclosure” of the invention requires that the invention be made “reasonably available to the public.” Neither public uses nor private sales satisfy this requirement. This is a long post, because the issues are both important and interesting. In the end, I suggest a panel rehearing in the case because I believe that the Federal Circuit unfairly found forfeiture of key arguments whose resolution would help clarify the law. (more…)

Federal Circuit Slices the Bologna Thin with IPR Rehearing Waiver Decision

Voice Tech Corp. v. Unified Patents, LLC, No. 2022-2163 (Fed. Cir. Aug. 1, 2024)

Unified Patents is paid by its members to fight against non-practicing entity (NPE) patent assertions — often by challenge patent validity via inter partes review.  In this case, Unified challenged Voice Tech’s U.S. Patent No. 10,491,679 which covers technology for controlling a computer via a mobile device using voice commands. At the conclusion of the IPR, the Patent Trial and Appeal Board (PTAB) sided with Unified – finding all challenged claims (1-8) of the ‘679 patent unpatentable as obvious over the combination of two prior art references, Wong and Beauregard.  The PTAB also denied Voice Tech’s request for rehearing. On appeal, the patentee won a minor battle on waiver, but ultimately lost on the merits.

NO FAKES Act: Unpacking the New Bipartisan Bill on Digital Replicas

Patent, , , , , , , , , , , , , , , , ,

Senators aim to rein in digital replicas with the “NO FAKES” Act which proposes a limited federal right to control one’s likeness using some DMCA-like notice-and-takedown elements.

Guest post by Professor Justin Hughes

This week, Senators Blackburn, Coons, Klobuchar, and Tillis introduced the bipartisan “NO FAKES” Act in Congress, a bill that has been under discussion for months and is intended to provide centerpiece legislation addressing the problem of digital replicas.  The recording industry (RIAA) and the actors’ union (SAGAFTRA) have been the leading proponents of such a law.  Senate Judiciary staff led a process with those groups–and with the Motion Picture Association (MPA)–that went through a long series of drafts.  AI companies were also part of the drafting process.

The bill is substantively complex and structurally complicated, partly the result of so many cooks in the kitchen.  What follows here are only the bill’s basics – as well as some concerns. (more…)

Presumption of Injunction: How the RESTORE Act Aims to Re-Empower Patent Holders

Patent, , , , , , , , , , , , , , , , ,

by Dennis Crouch

For the vast majority of American history, a judgment of patent infringement (by a court sitting in equity) led almost directly to injunctive relief barring ongoing infringement.  This construct was flipped by the Supreme Court’s 2006 decision in eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006), a case which served as the first major step of weakening patentee rights over the past two decades.  Now, a new bipartisan bill aims to restore the pre-eBay status quo. The Realizing Engineering, Science, and Technology Opportunities by Restoring Exclusive (RESTORE) Patent Rights Act of 2024, introduced by Senators Coons (D-Del.) and Cotton (R-Ark.), with a House companion bill from Representatives Moran (R-Texas) and Dean (D-Pa.), seeks to reshape and repair the availability of injunctive relief for patent holders.  As you’ll see, one nice element of the Bill is that it simply adds 1 sentence – creating a rebuttable presumption (more…)

Lovevery Argues that APEX Jurisdiction Holding Undermines Anti-Counterfeiting Efforts

Patent

by Dennis Crouch

This is my third post about SnapPower (SnapRays) v. Lighting Defense, and the Federal Circuit’s holding that patentee’s who use Amazon’s patent enforcement process (APEX) to block infringing product sales open themselves to personal jurisdiction in the home state of the accused infringer. SnapPower v. Lighting Def. Group, 100 F.4th 1371 (Fed. Cir. 2024). In my view, the Federal Circuit has gone too far with aggressive personal jurisdiction in this case, and the patentee Lighting Defense has petitioned for en banc rehearing on the issue.

Most recently, toy-maker Lovevery has filed an amicus brief supporting en banc review. (more…)

Deja Vu All Over Again: SCOTUS Asked Again to Revisit Patent Eligibility

Patent

Return Mail recently filed its petition for certiorari with the Supreme Court, seeking a broader scope of patent eligibility under 35 U.S.C. § 101. You may remember that Return Mail won its case before the Supreme Court a few years ago. Return Mail, Inc. v. United States Postal Service, 587 U.S. 618 (2019) (federal agencies are not “any person” under the AIA and therefore cannot challenge patents via IPR). (more…)

Obtaining vs. Maintaining: How SoftView v. Apple Reshapes Patentee Estoppel

by Dennis Crouch

This is our second discussion of collateral estoppel in as many days.  Yesterday I wrote about Koss v. Bose, a case where the Federal Circuit concluded that a district court’s final judgment of invalidity had a preclusive effect on USPTO IPR analysis — rendering the patentee Koss’s appeal moot.   Today’s focus is on SoftView v. Apple, and a focus on the USPTO’s estoppel regulations as they apply between an IPR and reexamination proceeding. Case No 23-1005 (Fed. Cir. July 26, 2024). (more…)

Clever Pleading Can’t Save Koss’s Patents from Issue Preclusion Invalidity

Patent

by Dennis Crouch

Koss Corporation v. Bose Corporation, 22-2090 (Fed. Cir. July 19, 2024)

In its final written decisions, the PTAB found a number of Koss patent claims invalid and Koss appealed to the Federal Circuit. In the end, though the appellate panel found the appeals moot because all the claims had been invalidated in parallel district court litigation. Although the prior litigation involved a different party (Plantronics), Bose was able to take advantage of that invalidation decision under the doctrine of non-mutual collateral estoppel established by the Supreme Court in Blonder-Tongue Lab’ys, Inc. v. Univ. of Ill. Found., 402 U.S. 313 (1971).

Koss attempted a clever pleading trick (more…)

Patent Puzzles after the Supreme Court’s 2024 Administrative Law Cases: Stare Decisis, Rulemaking, and Discretion

Patent

Guest post by Arti K. Rai, Elvin R. Latty Distinguished Professor of Law and Co-Director, Center for Innovation Policy at Duke Law

In a flurry of recent decisions, the Supreme Court has continued its skepticism of administrative agencies.  Although these decisions may not have as significant an impact in patent law as in other areas, they do pose interesting puzzles with respect to stare decisis as well as agency rulemaking and discretion that will provide many litigation opportunities going forward.

The Shift Towards Primary Examiners: Implications for Patent Prosecution

Patent

by Dennis Crouch

In recent years, the United States Patent and Trademark Office (USPTO) has undergone a significant shift in its examiner composition, with real implications for patent prosecution strategies.

Our data reveals a dramatic drop in the percentage of assistant examiners over the past decade. Prior to 2015, over 35% of patents were examined by assistant examiners. Since 2020, this number has plummeted to less than 20%. But these assistant examiners did not simply disappear. (more…)

Ejusdem Generis Goes to War in Reservist Pay Dispute

Patent

by Dennis Crouch

Although not a patent case, Feliciano v. Department of Transportation merits attention as one of only two Federal Circuit cases granted certiorari for the October 2024 Supreme Court term, alongside the veterans benefits case of Bufkin v. McDonough.

In Feliciano, the Supreme Court will consider whether federal civilian employees who are called to active military duty are entitled to differential pay even if their service is not directly connected to a declared national emergency. The case stems from the Federal Circuit’s interpretation of the differential pay statute, 5 U.S.C. § 5538, which requires federal agencies to provide supplemental pay to federal employees called to active duty when their military salary is less than their civilian salary.

In Miller Mendel, Inc. v. City of Anna, Texas, No. 2022-1753 (Fed. Cir. July 18, 2024), the Federal Circuit affirmed a district court’s judgment on the pleadings that the asserted claims of Miller Mendel’s U.S. Patent No. 10,043,188 (‘188 patent) are ineligible for patent protection under 35 U.S.C. § 101. The court also affirmed the denial of the defendant’s motion for attorneys’ fees under 35 U.S.C. § 285.

USPTO Issues 2024 Guidance on Patent Eligibility for AI Inventions

Patent,

by Dennis Crouch

Earlier this week I was reviewing some of the USPTO’s eligibility examples, noting that they were all quite old.  As if on cue, the Office has released a new set of updated guidelines – focusing on Artificial Intelligence related inventions and including three new examples.  In Bilski, the Supreme Court explained that the best way to understand whether a particular claimed invention is directed to an “abstract idea” is to look back on old examples for guidance.  The USPTO has found that a good way to administer this approach is to provide examples of situations that pass or fail the test.  Here, they introduce three new examples 47, 48, and 49.  And, while the Alice/Mayo test for analyzing subject matter eligibility has not changed, the new guidance is helpful as AI technology rapidly develops.   The USPTO continues to be open to issuing patents on AI inventions, including the use of AI. However, there must be a technical solution to a technical problem.

Although the guidance is effective July 17, 2024, the USPTO is open to comments via the regulations.gov portal.  The agency has provided two updated flow charts for its analysis that are included below. Although the USPTO guidance is not binding law,  it is the guidebook that examiners will be trained upon and required to use.  As such, any patent attorney operating practicing in the AI area should dig through these examples and the particular cases chosen by the Office as representative.

The Phantom Menace: Federal Circuit Upholds Judge Connolly’s Investigative Powers Even After Dismissal

Patent

by Dennis Crouch

In Backertop Licensing LLC v. Canary Connect, Inc., the Federal Circuit addressed the scope of a district court’s inherent authority to investigate potential litigation misconduct. Chief Judge Connolly of the District of Delaware had initiated an inquiry into dozens of patent infringement cases filed by plaintiff LLCs associated with IP Edge, a patent monetization firm, and Mavexar, an affiliated consulting shop. The district court was concerned that the real parties in interest may have been concealed, that fictitious patent assignments were filed with the USPTO to shield those parties from liability, and that the plaintiff LLCs’ attorneys may have violated the Rules of Professional Conduct by taking direction from Mavexar without their formal-clients’ informed consent.
