Patent Prosecution

We love patent law and for more than 35 years, Sterne Kessler has been preparing and prosecuting patent applications. We prosecute and enforce utility and design patents for companies with extensive, active patent portfolios, as well as small start-up companies that rely on the patent system to obtain funding and to head off competition. The patents that we acquire for these innovators are sometimes their most important assets.

Why choose Sterne Kessler?

  • Quality Counts - we prosecute when the stakes are high.

  • Our attorneys, patent agents, and technical specialists have deep technical expertise in a wide range of fields.

  • We provide strategic counsel from idea conception, to product, to launch and beyond.

  • We are regularly recognized by companies and top organizations for patent prosecution.

Our experience with patents does not end with patent preparation and prosecution. We apply our knowledge of the laws and workings of the Patent Office to advise on patent office litigation and claim interpretation for infringement and validity opinions.

  • Phillips Foods

    From local sensation to global competitor

    When Phillips Foods developed a less expensive alternative to a jumbo lump of crab meat, Sterne Kessler was immediately called to protect its process and product as valuable assets. We searched and reviewed the closest prior art to craft the broadest possible patent protection for the method of manufacturing a formed lump of crab meat.
