In a set of astonishing identical Director Review decisions, the Acting USPTO Director discretionarily denied five IPR petitions whose proceedings would have concluded over seven months before the underlying patent infringement suit would have gone to trial.

The patent statute 35 U.S.C. § 325(d) allows the USPTO Director to deny institution of an IPR when “the same or substantially the same prior art or arguments previously were presented to the Office.” In IPR practice, relying on prior art that already had been before the PTO is perfectly acceptable. Under the 2020 decision in … Continue Reading
As provided by statute at 35 U.S.C. § 311(b), a petitioner in an inter partes review (IPR) may challenge the claims of a patent “only on the basis of prior art consisting of patents or printed publications.” Does this provision permit IPR challenges based on Applicant Admitted Prior Art (AAPA) ― art identified in the … Continue Reading

On March 18, 2024, the United States Patent and Trademark Office (USPTO) issued a Memorandum containing guidance to help patent examiners analyze claim language that may be interpreted as “means-plus-function” or “step-plus-function” language under 35 U.S.C. § 112(f). The USPTO said that the Memorandum was not a change in practice for examiners. Sometimes, however, how something … Continue Reading
The United States Patent and Trademark Office (USPTO) recently published updated guidance emphasizing a very flexible approach to determining obviousness under 35 U.S.C. § 103, consistent with the U.S. Supreme Court’s opinion in KSR v.

A number of district courts, as well as the Court of Appeals for the Federal Circuit, have weighed in on whether and to what extent a patent challenger in an inter partes review (IPR) before the Patent Trial and Appeal Board may be estopped from making prior art based challenges in a district court litigation. … Continue Reading

We previously wrote that a co-pending ITC Section 337 investigation virtually guarantees that the Patent Trial and Appeal Board (PTAB) will exercise its discretionary power to deny institution under 35 U.S.C. §§ 314(a) and 324(a) when considering a petition for inter partes review (IPR) or post-grant review (PGR). See ITC Section 337: Kiss of Death … Continue Reading
When considering a petition for post-grant review (PGR) or inter partes review (IPR), the Patent Trial and Appeal Board (PTAB) has discretion to deny institution under 35 U.S.C. §§ 314(a) and 324(a).

In United States v Arthrex, the Supreme Court held that 35 U.S.C. §6(c), which sets forth the authority of Patent Trial & Appeal Board (“PTAB”) Administrative Patent Judges (“APJs”), is unconstitutional because APJs effectively wield the power of principal officers (who require Senate confirmation) while being appointed as inferior officers (who do not require Senate confirmation) … Continue Reading

In patent disputes involving complex technologies, especially when the disputed patent was developed in an early stage of the technical field, research papers and similar publications are oftentimes relied on to make obviousness-based invalidity challenges. It is common for such research papers to include predictions or aspirations with regards to potential future developments in the … Continue Reading
One of the most common responses to being sued for patent infringement is a petition to the USPTO’s Patent Trial and Appeal Board (PTAB) challenging the validity of the patent. To avoid duplication of effort, either the Board or the tribunal can defer to the other. According to a recent decision, the U.S. International Trade … Continue Reading
The Patent Trial and Appeal Board (PTAB) is an administrative law body of the US Patent and Trademark Office (USTPO) that determines disputes over the issuance, reissuance, and cancellation of patent claims. The PTAB has become well known to patent litigants since the implementation in 2012 of new proceedings, including Inter Partes Review (IPR), for … Continue Reading
In 2020, the PTAB increasingly denied otherwise meritorious petitions for review under its discretionary authority, as my partner Steve Auvil and I recently discussed. Many such denials were made in view of co-pending litigation under the so-called Fintiv factors adopted last May. The reaction to the PTAB’s approach was vocal and divided, and the USPTO … Continue Reading
