Unified provides comments for USPTO Initiatives To Ensure the Robustness and Reliability of Patent Rights

Unified Patents provided comments to the USPTO's RFC on USPTO Initiatives To Ensure the Robustness and Reliability of Patent Rights and those were recently published. The comments largely support the USPTO's aims to bolster certain requirements during prosecution, such as requiring clearer written description support for claims and curtailing continuation abuse. The comments were provided by in-house counsel, Michelle Aspen and Jonathan Stroud.

SCOTUS Amicus Filed by Unified Edge, Supporting Curb on Over-Broad Patent Claims

On February 10, 2023, Unified Edge filed an amicus brief with the Supreme Court concerning the test for whether a patent has met the statutory requirement for enablement—i.e., the requirement that the specification sufficiently disclose the claimed invention in such full, clear, and exact terms as to enable any person skilled in the art to make and use it. 

The brief explains why the Supreme Court should maintain—across all fields of endeavor, including high tech—the Federal Circuit’s vigorous check on functional patent claims that the Federal Circuit has applied over decades of its case law (which in turn rests on 170 years of the Supreme Court’s jurisprudence). The fact-intensive investigation into enablement required by the Federal Circuit's Wands factors provides the appropriate, flexible framework for Patent Office examiners, fact-finders, trial court judges, and reviewing appellate courts to apply in assessing compliance with the statutory requirement for enablement. 

Reversal—and replacement of the full scope enablement test with Amgen’s proposed permissive standard—would invite patentees even further to pursue wildly unsupported functional claims in the Patent Office across a wide range of industries, threatening innovation and contributing to already out-of-control litigation defense and settlement costs.

GE patent dropped from Access Advance HEVC pool after successful Unified challenge

,

Some patent holders and pools designate their patents as relevant or essential to a standard without proper scrutiny or analysis. As part of an ongoing series examining this dubious practice, we highlight U.S. Patent 10,057,603. The ’603 patent is owned by GE Video Compression. Access Advance LLC had identified this patent as purportedly essential to the H.265 (HEVC) standard as part of the Access Advance Patent Pool. But after an ex parte reexamination initiated by Unified Patents led to a significant narrowing of the claim, Access Advance no longer lists this patent as essential. 

Access Advance had identified claim 1 of the ’603 Patent as allegedly essential. That claim recites:

1. A decoder for decoding a data stream including encoded data of a video, the decoder comprising:

an entropy decoding engine configured to decode data from the data stream based on an arithmetic decoding scheme to obtain a sequence of symbols, 

wherein, with respect to at least one symbol of the sequence of symbols, the entropy decoding engine is configured to:

select a context corresponding to the at least one symbol, and 

entropy decode the at least one symbol using the selected context based on the arithmetic decoding scheme, which includes updating a probability model associated with the selected context at one of a first update rate under a high-efficiency mode of entropy decoding and a second update rate, that is lower than the first update rate, under a low-complexity mode of entropy decoding; and

a reconstructor configured to reconstruct at least a portion of the video based on the sequence of symbols.

Unified filed its reexamination request on December 21, 2020, based on prior art that clearly disclosed claim 1. Given the strength of the prior art, the USPTO quickly determined that a substantial new question of patentability had been raised. A formal rejection issued on June 25, 2021, detailing how the prior art rendered the claim invalid. Of importance here, the claims were found to only cover the specific, corresponding disclosures in the specification rather than the broad, functional language that was clearly taught by the prior art. In the following months, the patent owner attempted to dissuade the examiners of this interpretation, but those attempts failed, and the reexamination concluded on January 26, 2022. 

Under U.S. law, a patentee is only allowed to use the broad, functional language at issue here if it is willing to be limited to the specific disclosures in the patent that correspond to the functional language. Patent asserters like Access Advance have tried to shirk this requirement when asserting their patents, taking advantage of claim language that looks broad on its face. Worse, Access Advance kept this patent in its May 2022 list of allegedly-essential patents only to finally remove it from its October 2022 list, nearly 10 months after the reexamination concluded.

Hence, the importance of formal scrutiny is demonstrable. Overbroad assertions of hundreds of patents that allegedly cover critical technical standards can, and should, be meaningfully analyzed. In the end, the public benefits when it is clear which are the truly valid and essential patents. Challenges to such assertions have a proven track record of sifting the wheat from the chaff.

Unified Succeeds in RPI Decisions

For the past decade, across more than 300 proceedings, Unified Patents has won every real party-in-interest (RPI) challenge—whether at institution, on final written decision, or before the Federal Circuit.  

Unified’s status as the sole RPI was challenged in its first filed IPR, where the Board held that Unified was the sole RPI. Unified Patents Inc. v. Clouding IP, LLC, IPR2013-00586, Paper 9 (Mar. 21, 2014) (members were not found to be RPIs, where there was no evidence of funding or control of the particular IPR; challenged claims were later cancelled in a Final Written Decision issued April 26, 2015). Unified overcame every such challenge in the proceeding years. Today, RPI designations are rarely challenged and largely settled law.

Proven Networks proven to be PAE in public interest statements

,

On January 27, 2022, Unified Patents filed a public interest statement in the ITC on the Proven Networks v. NetApp (inter alia) investigation. Unified focused on Proven Networks' status as a litigation funded, investment-driven NPE run and controlled by the Russ, August, and Kabat firm. Read the public statement below and also find comments from a member of Congress, NetApp, and others.
