Posts in USPTO

This week on IPWatchdog Unleashed, I speak with Todd Walters, who is Chair of the Patent Office Litigation practice group at Buchanan. We explore the current state of Patent Trial and Appeal Board (PTAB) practice and the growing tension among stakeholders as policy changes continue to reshape post-grant proceedings. We reflect on the intensity of opinion from patent owners and petitioners and discuss the high financial stakes and strategic importance of AIA proceedings.

The U.S. Patent and Trademark Office (USPTO) de-designated two decisions having to do with real-parties-in interest from precedential status on Tuesday. The Office de-designated Proppant Express Invests., LLC v. Oren Techs., LLC, IPR2017-01917, Paper 86 (PTAB Feb. 13, 2019); and Adello Biologics LLC v. Amgen Inc., PGR2019-00001, Paper 11 (PTAB Feb. 14, 2019). According to a USPTO email sent Tuesday, both decisions conflict with the decision in Corning Optical Communications RF, LLC v. PPC Broadband Inc., IPR2014-00440, Paper 68 (PTAB Aug. 18, 2015) (precedential).

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Tuesday affirmed two final written decisions from the Patent Trial and Appeal Board (PTAB) in inter partes review (IPR) proceedings, concluding that the board did not err in finding claims of two Eagle View Technologies, Inc. patents unpatentable as obvious. Eagle View Technologies, Inc. had appealed the PTAB’s decisions, which held that claims of its U.S. Patent Nos. 8,670,961 and 8,078,436 were obvious over a combination of prior art references. The patents, both titled “Aerial Roof Estimation Systems and Methods,” share a common specification and relate to systems and methods that allow estimates involving roofs on buildings to be created remotely. The patents teach remotely generating a roof estimate report by analyzing multiple aerial images of a building to determine the area, shape, and slope of the roof.

Panelists at IPWatchdog’s Virtual PTAB Masters Program 2026 last week had some cynical views on chances for pending patent reform bills, while on Friday other experts offered insights into developments at the U.S. Court of Appeals for the Federal Circuit (CAFC) with respect to review of Patent Trial and Appeal Board (PTAB) cases. Speaking on Thursday’s panel, titled “Capitol Hill & PTAB Politics: Innovation Policy, Congressional Oversight and Mid-term Elections,” panelists first addressed the chances of bills such as the Patent Eligibility Restoration Act (PERA) and the Promoting and Respecting Economically Vital American Innovation Leadership (PREVAIL) Act advancing this year.

U.S. Patent and Trademark Office (USPTO) Deputy Director Coke Morgan Stewart joined IPWatchdog’s Founder and CEO Gene Quinn this morning to kick off the Virtual PTAB Masters Program 2026. Discussing the many procedural changes that have been implemented at the Patent Trial and Appeal Board (PTAB) under first Stewart as Acting Director and then current Director John Squires’, Stewart urged patent owners responding to petitions at the PTAB to tell their stories and petitioners to focus on patents in need of clear “error correction.”

The U.S. Court of Appeals for the Federal Circuit (CAFC) has denied another petition for writ of mandamus seeking to challenge the U.S. Patent and Trademark Office’s (USPTO’s) so-called settled expectations doctrine, which was introduced by then-Acting Director Coke Morgan Stewart. In the present case, Google sought mandamus relief after the USPTO denied its petitions for inter partes review (IPR) of VirtaMove Corp.’s U.S. Patent No. 7,519,814 patent because “the patent[] ha[s] been in force for more than 14 years, creating strong settled expectations.”

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Friday vacated and remanded a final written decision from the Patent Trial and Appeal Board (PTAB) in an inter partes review (IPR) proceeding. The court concluded that the Board erred by requiring petitioner Guardant Health, Inc. to show a motivation to combine steps that were already disclosed in sequence in a single prior art reference.

The U.S. Court of Appeals for the Federal Circuit (CAFC) today affirmed the Patent Trial and Appeal Board’s (PTAB’s) decision sustaining an examiner’s rejection in an ex parte reexamination of claims of EcoFactor, Inc.’s patent relating to smart thermostat technology. Google filed for reexamination of U.S. Patent No. 8,412,488 in 2021 and an examiner rejected claims 1, 3 through 9 and 11 through 16 in a non-final office action as unpatentable over the combination of U.S. Patent No. 2004/0117330 (“Ehlers”) and U.S. Patent No. 2005/0159846 ) (“Van Ostrand”) and claims 2 and 10 as unpatentable over Ehlers, Van Ostrand, and a third patent, No. 6,789,739 (“Rosen”).

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Wednesday reversed in part, vacated in part, and remanded a final written decision from the Patent Trial and Appeal Board (PTAB) in an inter partes review (IPR) proceeding filed by Apple, Inc.. The court concluded that the Board was precluded from finding the challenged claims of a patent owned by Smart Mobile Technologies LLC patentable, where a related patent with substantially similar claims had been found unpatentable in a prior IPR.

In the latest episode of IPWatchdog Unleashed, I sat down with my good friends Brad Close, who is the Executive Vice President of Transpacific IP, and Jim Carmichael, a former judge on the Board of Patent Appeals and Interferences and founder of Carmichael IP. Brad, Jim and I engaged in a candid conversation that provides our unvarnished assessment of the Patent Trial and Appeal Board (PTAB), where it started historically, where it is today, and where it may finally be headed. Bottom line: the PTAB is no longer the automatic execution squad it once was, but durable patent rights will require reform well beyond the agency level.

U.S. Patent and Trademark Office (USPTO) Director John Squires on January 15 issued a Director Review decision, which he then designated as informative on January 16, in favor of Micron Technologies, vacating two Patent Trial and Appeal Board (PTAB) decisions granting institution of inter partes review (IPR) for Yangtze Memory Technologies. The decision addressed the issue of real party in interest (RPI), which Squires said Micron had sufficiently disputed, while Yangtze failed to rebut the evidence presented and show that it had named all RPIs.

A group of conservative leaders on Wednesday sent a letter to the Director of the National Economic Council, Kevin Hassett, and Chief of Staff to President Trump, Susie Wiles, strongly supporting the U.S. Patent and Trademark Office’s (USPTO’s) Notice of Proposed Rulemaking (NPRM) issued in October, titled “Revision to Rules of Practice before the Patent Trial and Appeal Board.” The NPRM modifies the rules of practice for inter partes reviews (IPRs) before the Patent Trial and Appeal Board (PTAB), with the stated goal being “to focus inter partes review proceedings on patent claims that have not previously been challenged in litigation or where prior litigation was resolved at an early stage.” The deadline for comments was December 2 and the Office has received 11,442 total submissions.

There are lots of familiar recommendations to make U.S. businesses more competitive globally. All are valid, but none are particularly creative or original. One solution that hasn’t been pursued is not only simple, a variation of it has been implemented by America’s largest and most aggressive economic competitor: remove the filing fees for inventors and intellectual property (IP)creators under 18.

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Tuesday vacated and remanded a final written decision from the Patent Trial and Appeal Board (PTAB) in an inter partes review (IPR) proceeding. The court concluded that the Board erred by denying petitioner Apple Inc. an adequate opportunity to respond to a new claim construction argument raised by patent owner Smart Mobile Technologies LLC after the IPR was instituted. Apple challenged U.S. Patent No. 9,191,083, owned by Smart Mobile, which is described as a “portable and wireless enabled” network box designed to transmit and receive multiple data streams simultaneously. The technology at issue involves using a “plurality of antennas” to handle these simultaneous data streams. After instituting the IPR, the Board ultimately determined that Apple had not shown by a preponderance of the evidence that the challenged claims of the ‘083 patent were unpatentable as obvious.
