In Trusted Knight v. IBM, Judge Chen granted IBM’s motion to stay the patent case pending inter partes review.
Trusted Knight Corporation and IBM; the patent-infringement litigation is paused while the Patent and Trademark Office completes its inter partes review.
What happened
Trusted Knight Corporation sued International Business Machines Corporation (IBM), alleging that IBM infringed Trusted Knight’s patent concerning protection against keylogging malware. IBM asked the court to pause the case while the Patent and Trademark Office reviewed all currently challenged patent claims.
The court found that the case was still in an intermediate stage: claim construction had occurred, but discovery was incomplete, no trial date had been set, and no summary-judgment motions had been prepared. The court also concluded that the patent review could simplify the case and that Trusted Knight had not shown enough harm from the delay, although the companies’ alleged competition weighed somewhat against a stay.
Judge Edward M. Chen granted IBM’s motion to stay pending inter partes review. The parties must file a joint status report 30 days after the Patent and Trademark Office issues its decision.

Background
Trusted Knight Corporation sued International Business Machines Corporation (IBM) for allegedly infringing U.S. Patent No. 9,503,473, which concerns systems and methods for protecting against keylogging malware that uses form-grabbing techniques to steal financial and identity information from users’ browsers. The patent issued on November 22, 2016. The opinion states that this was the second patent-infringement case between the parties and that the ’473 patent incorporated by reference the disclosure of an earlier patent.
The court had issued a claim-construction order addressing one term, and discovery was ongoing. The court had not adjudicated any substantive motions, had not set a discovery cutoff, and had not set a trial date. IBM moved to stay the litigation while the Patent and Trademark Office’s Patent Trial and Appeal Board conducted inter partes review, an administrative proceeding that examines the validity of patent claims.
Legal Standard
The court explained that federal courts have inherent authority to manage their dockets, including by staying a patent case during a parallel Patent and Trademark Office proceeding. Courts generally consider three factors: the stage of the litigation, whether the review will simplify the issues, and whether the stay would unfairly prejudice or tactically disadvantage the party opposing it. IBM, as the party seeking the stay, had the burden of showing that a stay was appropriate.
Analysis
The first factor favored a stay. Although claim construction had already occurred, the court found that no discovery had yet occurred, no summary-judgment motions had been prepared or filed, and no trial date had been set. The court therefore treated the case as sufficiently undeveloped for a stay.
The second factor also favored a stay. The inter partes review covered all currently challenged claims. The court reasoned that the Patent Trial and Appeal Board might cancel or modify claims, narrowing or eliminating the need for further proceedings. Even if the claims survived, the court could benefit from the Board’s analysis, and IBM could be barred from later raising arguments that it had raised or reasonably could have raised in the review proceeding. The court also noted that it was possible the Board could invalidate every claim of the patent, although the court described that result as not likely.
The third factor addressed prejudice. The court found that the timing of IBM’s review petition, IBM’s prompt request for a stay after review was instituted, and the early status of the review proceedings favored a stay. Trusted Knight argued that delay could cause stale evidence, faded memories, and lost documents, but the court stated that delay inherent in the review process, by itself, did not establish undue prejudice. The court also rejected Trusted Knight’s contention that IBM sought the stay in bad faith to avoid discovery obligations, finding nothing in the record suggesting a bad-faith reason for the request.
Trusted Knight’s strongest argument concerned the parties’ alleged direct competition and the potential for marketplace harm from delayed enforcement of patent rights. The court assumed, for purposes of its analysis, that the parties were direct competitors and found that this consideration weighed moderately against a stay. It nevertheless concluded that the other factors favoring a stay predominated.
Disposition
Judge Edward M. Chen granted IBM’s motion to stay pending inter partes review. The parties were directed to file a joint status report 30 days after a decision from the Patent and Trademark Office. The order disposed of Docket No. 99.
