Liza J. M. Heinig


Practice Areas

Mrs. Heinig’s practice focuses on intellectual property issues in the mechanical and related arts.  She works closely with clients to develop, manage, and carry out patent and non-patent strategies to protect and leverage the value of their intellectual property.  Mrs. Heinig has prepared and prosecuted hundreds of U.S. and foreign patent applications in technologies including heavy equipment and work machines, sporting goods, biomechanical devices, surgical techniques and tools, household products, automotive components, manufacturing processes and equipment, and communication devices.  She also has experience working with patentability searching and analysis, patent appeals, infringement and validity opinions, and intellectual property due diligence projects.

Mrs. Heinig enjoys working with inventors to develop and achieve the best possible protection for their ideas.  Mrs. Heinig considers client communication and inventor education to be significantly interesting and rewarding aspects of her practice. She thus has become an adjunct professor at Case Western Reserve University School of Law (2012-2020), where she supervises student IP and business development work at Case’s Intellectual Property Venture Clinic.
