The company's patent litigation history reflects that of an operating company defending its technology. Based on the provided data, Lexmark has appeared as a defendant in one tracked case and has not been a plaintiff. This defensive posture is consistent with a technology manufacturer being targeted by a patent assertion entity.

The single tracked case, filed in 2012 in the Southern District of California, was MPHJ Technology Investments, LLC v. Lexmark International, Inc.. The plaintiff, MPHJ, was a non-practicing entity widely described as a "patent troll" for its practice of suing numerous small businesses over patents related to scan-to-email technology. MPHJ's litigation campaign attracted scrutiny from state attorneys general and the Federal Trade Commission (FTC), which took action against the firm for using deceptive tactics in its demand letters.
