In-House Patent Lawyers Can Design Around Patents They Wrote For Their Former Employer

In house lawyers, even patent lawyers, can jump to a competitor, as long as they don’t violate duties owed to their former employer/client. Furthermore, patent lawyers are free to conduct for their new employer infringement analyses of patents they wrote for their former employer. That is the holding in a 2016 Massachusetts case, Gillette Co. v. Provost. The court wrote: “It is perfectly lawful for Gillette’s former patent attorney to help a competitor avoid infringing Gillette patents, so long as he does not disclose or use any confidential information obtained from Gillette.”

The lawyer in question worked for a number of years as an in-house patent attorney for Gillette. He then took a job as General Counsel at ShaveLogic (Dollar Shave Club), where his job responsibilities included helping ShaveLogic design around patents he had prosecuted while at Gillette. Gillette sought an injunction preventing him from doing that work on the basis that the lawyer had breached the fiduciary duty a lawyer owes a former client under Massachusetts Rule of Professional Conduct 1.9. The rule prohibits a lawyer from representing a second client in the same or a substantially related matter in which the second client’s interests are materially adverse to the interests of the former client

The court held that the design-around work did not violate the rule because Gillette could not show that it involved misuse of Gillette’s confidential information; the wrong Rule 1.9 is designed to prevent. Patents are pubic documents, and opining on whether a particular product infringes a patent requires nothing more than comparing that product to the public patent. Confidential information could not help. The court explained that if the in-house lawyer’s new job had involved assessing the validity of patents he prosecuted at Gillette, the result might have been different. In that circumstance the lawyer might have confidential information concerning prior art or inventor behavior that would aid his analysis.
