Gator Bio prevailed at the ITC after a full hearing and later secured dismissal of infringement claims in federal court.
PALO ALTO, Calif., Aug. 26, 2026 /PRNewswire-PRWeb/ -- Gator Bio today confirmed the outcome of two U.S. patent proceedings brought against it by Sartorius Bioanalytical Instruments, Inc. Gator Bio prevailed at the U.S. International Trade Commission after a full hearing. In February 2026, the U.S. District Court for the Northern District of California dismissed additional Sartorius infringement claims.
Sartorius began its U.S. International Trade Commission case by asserting claims from four U.S. patents against Gator Bio's BLI products. Before the hearing, Sartorius itself withdrew three of those patents and all but one claim of the fourth. Gator Bio won on that remaining claim. The Administrative Law Judge found no infringement, and the Commission affirmed the no-infringement result and terminated the investigation with a final finding of "no violation." Sartorius did not appeal.
In February 2026, the U.S. District Court for the Northern District of California dismissed additional Sartorius infringement claims, including its claim of willful infringement, and described part of Sartorius's position as "self-contradictory." The remaining federal case is narrow and currently on hold.
"We developed this BLI technology and we built Gator Bio to keep improving it. When the case was heard in full, the finding was no violation. Our customers can keep running their assays and planning their next experiment."
Hong Tan, CEO, Gator Bio
What this means for customers
Nothing in these U.S. rulings prevents customers from continuing to buy or use Gator Bio products. The district court has said Sartorius is "unlikely to obtain injunctive relief," meaning unlikely to obtain an order that could stop or restrict future sales of Gator Bio products in the U.S., and three of the four patents in the federal case have now expired. These proceedings concern U.S. patent rights only and do not determine patent rights in Europe, Asia, or elsewhere. Laboratories worldwide continue to run Gator Bio systems with confidence.
The underlying orders are posted at gatorbio.com for customers and procurement teams who want to review the primary documents.
