Global patent dispute over agricultural equipment: Jon represented a Dutch company making innovative dairy cattle detection devices in a patent case brought by an Israel-based competitor. The disputed technology involved electronic behavior detectors, and Jon sought testimony from a series of experts included leading animal behavior scientists. The litigation entailed international depositions, as well as patent battles in both the U.S. and Europe. Jon obtained a summary judgment of noninfringement on his client’s behalf on the eve of the trial.

Generator manufacturer defense hinging on long-archived evidence: Jon successfully defended his generator company client, Kohler Co., against a complaint brought by another major manufacturer directed at Internet control of the equipment. Jon worked with Kohler to find invalidating prior art, including long-deleted Internet evidence he retrieved, that proved the technology was not patentable. The jury for the weeklong trial, in U.S. District Court in the Eastern District of Wisconsin, found that the patent had not been infringed upon, and were invalid.

Enforcement of trailer patent: Jon successfully tried a weeklong jury trial in Madison, Wisconsin on behalf of a large trailer manufacturer enforcing its patent related to an innovative advance in sidewall construction. The jury awarded a multimillion dollar verdict in favor of the client.

Defense of LED flashlight distributors: In this matter directed at LED flashlight technology, Jon represented a number of flashlight manufacturers and national retailers. During the course of the case, his clients discovered that the plaintiff’s evidence of its conception date was suspect. Using a former FBI forensic document examiner, Jon proved that the plaintiff’s evidence was falsified. The judge in the four-day bench trial not only found the plaintiff’s patent unenforceable, but awarded attorneys’ fees to all the defendants.

Patent defense on behalf of a major luggage manufacturer: A competitor of Jon’s client, Ricardo Beverly Hills (RBH), one of the nation’s largest luggage manufactures, filed a complaint alleging patent infringement. The case involved the addition of what seemed to RBH to be an old feature (zippers) appended to wheeled luggage. The jury in U.S. District Court for the District of New Jersey found for RBH on all counts, and both absolved the defendant of infringement and invalidated the patent-in-suit.
