Emphasizing Context in Claim Construction

by Dennis Crouch

In Neonode Smartphone LLC v. Samsung Electronics Co., Ltd., the Federal Circuit has reversed Judge Albright's holding that claims of Neonode's US8095879 are invalid as indefinite.  No. 2023-2304 (Fed. Cir. Aug. 20, 2024) (non-precedential). The appellate panel concluded that Albright failed to properly consider the full context of the intrinsic record, particularly the prosecution history.

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

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  I had skipped a write-up of the non-precedential decision, but now Impact Engine has petitioned for en banc review, arguing that

Federal Circuit Slices the Bologna Thin with IPR Rehearing Waiver Decision

by Dennis Crouch

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.

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).

Sitting By Designation, Judge Albright Pens First Federal Circuit Opinion Vacating PTAB Decision for Failing to Consider Petitioner’s Reply Brief Claim Construction Arguments

by Dennis Crouch

The Federal Circuit's 2023 decision in Axonics, Inc. v. Medtronic, Inc. marked an important change in inter partes review procedure, ensuring petitioners have an opportunity to respond patentee's newly proposed arguments, with the hope of discouraging patent owners from holding-back ("sandbagging") at the institution stage.  Case-in-point is the Federal Circuit's recent Apple v. Omni MedSci decision authored by Judge Alan D. Albright sitting by designation.

Meta Claim Construction: Finding Meaning in the Meaning

by Dennis Crouch

One-E-Way, Inc. v. Apple Inc., 22-2020 (Fed. Cir. Aug. 14, 2023) (nonprecedential) (Opinion by Chief Judge Moore, joined by Judges Lourie and Stoll).

The district court sided with Apple on summary judgment, finding no infringement. On appeal, the Federal Circuit has affirmed, holding that Apple's accused Bluetooth products do not infringe One-E-Way's patents.  Although the parties had agreed to the construction of the "unique user code" term, they disagreed over the construction-of-the-construction.  On appeal, the court treated this meta-construction effectively as a form of claim construction -- looking for the ordinary meaning rather than a contract-like interpretation that would have looked more toward discerning the intent of the parties.
