The Court Can Wait; The Patent Office Cannot

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 Acting Director reasoned that the petitioner waited too long to file its IPR petitions because, even though … Continue Reading

$222M Jury Verdict Against Walmart in Trade Secret Case Reflects Growing Trend

Monetary awards in trade secrets cases continue to grab headlines in 2025.

Call It Out When You Think the Examiner Has Overlooked Prior Art

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

Federal Circuit Limits Use of Applicant Admitted Prior Art in Inter Partes Reviews

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

Whither Discretionary Denials? Read the Tea Leaves, or Follow the Bread Crumbs?(Part I)

Recent actions from the USPTO have engendered a great deal of discussion among the bar practicing before the Patent Trial and Appeal Board. On February 28, 2025, acting Director Stewart rescinded former Director Vidal’s Guidance Memorandum for handling discretionary denials in inter partes review proceedings before the Board. On March 24, 2025, Chief Judge Boalick … Continue Reading

Face the inMusic: A Corporate Patent Owner Cannot (Yet?) Recover the Lost Profits of a Subsidiary

The Federal Circuit has long held that “the general rule” of patent infringement damages law is “a patentee may not claim, as its own damages, the lost profits of a related company.” More than 15 years ago, one patent owner argued that an exception to this general rule should be when a subsidiary’s profits “flow … Continue Reading

Lost Profits for Unpatented Products Dry Up in Wash World

Wash World Inc. v. Belanger Inc. raises the question whether lost profit damages for patent infringement can extend to profits related to unpatented products sold with a patented product. As with many legal issues, including the lost profits issue I addressed in my recent post, the answer to the question is “sometimes.” In Wash World, … Continue Reading

The Intellectual Property Enterprise Court

In the UK, intellectual property (IP) infringement claims and other disputes in which IP is a major concern can be brought in either the High Court or in many cases the specialist Intellectual Property Enterprise Court (IPEC). Based at the Rolls Building in central London, the IPEC has a more streamlined procedure than the High … Continue Reading

Eyes Wide Open: Lost Profits Are Available in the Absence of Acceptable Non-Infringing Substitutes

Lost profit damages are notoriously difficult to recover in patent infringement cases. Lost profits damages are recovered in only a small percentage of cases that go to trial. Among the challenges in recovering lost profits under the Panduit test are that the patent owner must prove the absence of acceptable non-infringing alternatives (Panduit factor 2) … Continue Reading

ITC Confirms that a Disclaimer from a Later Patent Applies to the Same Term in an Earlier Related Patent

In a November 6, 2024 opinion in Certain Computing Devices Utilizing Indexed Search Systems and Components Thereof, the U.S. International Trade Commission (“ITC”) held that statements, disclaimers, and positions taken during the prosecution of a later patent apply to the construction and interpretation of the same term in an earlier related patent. Using this standard, … Continue Reading

US PATENT FEE INCREASES FOR 2025: Not (Nearly) as Bad as They Could Have Been

Earlier this year, as we discussed here, here, and here, the United States Patent and Trademark Office (USPTO or Office) proposed a number of sweeping changes to the Office’s patent fees, including a very steep set of fees for filing terminal disclaimers, later continuation applications, and three or more requests for continued examination (RCEs). The … Continue Reading

Dysfunctional Patent Families: The Federal Circuit Draws Two Different Conclusions on Whether a Later-Filed Patent Can Invalidate an Earlier-Filed One in the Same Family

When a patent application is allowed, the claims may not precisely cover everything that the applicant wants to protect. Rather than add new claims after a notice of allowance and prolong prosecution, applicants will commonly file one or more continuation applications to pursue different claims. The continuation has substantially the same specification and drawings as … Continue Reading

Part II: You’ve Got Patents! Or Someone Else Does… What are the Opportunities for Settlement Once They’re Asserted?

As noted in our related blog, only a small percentage of issued patents are ever asserted to be infringed with the filing of a lawsuit, even when infringed. Why? Because patent litigation is notoriously expensive and it’s risky for patent owners, as patent challengers more-often-than-not win and can invalidate the patent claims. Despite the costs … Continue Reading

Part I: You’ve Got Patents! Or Someone Else Does… What Happens When They’re Asserted?

The number of patents issuing each year has increased dramatically since the Patent Act of 1952 codified US patent law — from fewer than 50,000 patents issued per year to around 350,000 patents issued per year for the last decade. Yet over the last decade, the number of patent litigations filed has fallen to fewer … Continue Reading

Like a Tree Falling that No One Hears: AI-generated Disclosures Have the Potential to Block Patentability of Human Ingenuity

The U.S. Patent and Trademark Office continues to seek stakeholder input on AI-generated disclosures and patentability. Earlier this year, USPTO issued a public Request for Comment on the impact of artificial intelligence on prior art, the known understanding of a person of ordinary skill and how this effects patentability, specifically novelty and obviousness of a … Continue Reading

The USPTO’s Proposed Terminal Disclaimer Rule Change: It’s Radical, But Is It Legal?

In a May 10, 2024, Notice of Proposed Rulemaking (NPRM), the USPTO proposed sweeping changes in the rules governing the filing of terminal disclaimers. If the USPTO implements the proposed changes, entire patent families could be wiped out if just one claim of one patent in the family is found invalid over prior art. Patent … Continue Reading

Identifying a Single Biomolecule Means Single-molecule Detection Sensitivity

Every single word matters. Nowhere was this truer than when the Federal Circuit recently held, in an appeal from the Patent Trial and Appeal Board captioned Pacific Biosciences of California, Inc. v. Personal Genomics Taiwan, Inc., that an apparatus for identifying a single biomolecule meant examining one biomolecule alone and not inferring its identity from … Continue Reading

Intelligent AI Guidance from the USPTO Identifies Potential Perils

Much like word processing with spell check and other now commonplace digital tools were once only the stuff of science fiction, artificial intelligence (AI) is quickly becoming widespread in knowledge work including law practice. IP law is no exception. The use of AI in IP law practice has practical benefits, including the potential for enhanced … Continue Reading

The USPTO Proposes Steep RCE Fees. Will Patent Prosecution and Appeal Strategies Change?

As discussed in two of our recent blogs (here) and here), the United States Patent and Trademark Office (USPTO or Office) recently proposed substantial patent fee increases for continuing applications and terminal disclaimers.

Are the USPTO’s Proposed Terminal Disclaimer Fees the End of Continuing Applications?

As discussed in our previous blog (here), the United States Patent and Trademark Office’s (USPTO) has proposed substantial surcharges for filing continuing applications, depending on the timing of filing.

The Potential Mushroom Effect of the USPTO’s Mushrooming Patent Application Fees

The United States Patent and Trademark Office’s (USPTO) recently proposed patent fee increases could have far-ranging consequences for applicants looking to build a patent family from a single patent application.
