Patent Litigation

Patent rights are crucial to the success of many modern businesses. Keyhani LLC’s patent litigation and trial attorneys are prepared to defend your patent rights to the fullest extent of the law. We handle infringement litigation in federal courts across the country, from matters involving basic designs to complex computer software and biochemical patents. From sending cease and desist letters to potential infringers right up to the conclusion of trial, we are prepared to protect our clients’ patent rights.

Keyhani LLC is committed to protecting both clients who have allegedly infringed others’ patents and limiting the exposure and damages of those who have been unjustly accused of infringement. Our attorneys have successfully defended clients sued for patent infringement and have successfully asserted a variety of counterclaims including invalidity, trademark infringement, trade dress infringement, unfair competition, and tortious interference with existing or prospective business relations, laches, estoppel, and antitrust violations. Successfully establishing such counterclaims and defenses can be a valuable tool in settlement negotiations.

We provide clients with in-house, third-party and/or expert analysis and opinions on the likelihood of patent infringement and freedom-to-operate opinions. Such opinions can be a valuable tool in settlement negotiations. Regardless of the subject matter of the patent(s) at issue, we are committed to ascertaining the personal and professional goals that are important to our clients and strive to achieve these goals as quickly and efficiently as possible.

Our attorneys hold a variety of technical and advanced degrees, and our litigation trial team works closely with its patent prosecution experts to create effective patent infringement and defense strategies for our clients.
