HLF files and prosecutes patent applications at the USPTO in selected technologies, generally in the mechanical / device and chemical fields. HLF also offers a full range of patent-related opinions: patentability, validity, infringement, freedom-to-operate. The firm also consults on design around strategies and competitive landscape assessments.

HLF will file and prosecute each of the three types of patents available in the US (design, utility and plant) and coordinate with foreign counsel to file international applications as selected by clients. International patent filings are expensive so we counsel clients on filing strategies designed to optimize protection while keeping costs down.
