Profile
Ingrassia Fisher & Lorenz, LLP | IFL is an international intellectual property law firm of about 40 attorneys-at-law, patent attorneys, technical specialists, and data analysts in the United States, Europe, and China. The firm is also known under the LKGLOBAL brand in the United States, China, United Kingdom, and Ireland. Currently, the four primary offices are located in Detroit (Birmingham), London (Bath), Phoenix (Scottsdale), and San Diego (Del Mar), and the solo offices in Alabama, the Republic of Ireland (Dublin), Illinois, Minnesota, North Carolina, Oregon, and Pennsylvania. The firm continues to grow under common ownership and an exclusive partnership with the independent and Chinese owned entity of Beijing IFL Intellectual Property Agency (General Partnership) | Beijing IFL.
IFL’s cooperative and strategic approach is tailored to the specific needs of our clients. Our quality product and services within a multi-jurisdictional team that focus attorney efforts on substantive legal work and minimizing duplication of effort resulting in cost effectiveness.
Together with technology and informative and efficient client communication, IFL provides value-added efforts rather than fee maximization, which results in mutually beneficial and long-lasting relationships with our international clients rather than higher costs to our clients resulting from reciprocity arrangements with other law firms.
Legal Services
Most IFL professionals are attorneys-at-law with juris doctorates, and all professionals have technical degrees that include advanced degrees and doctorates to support numerous fields of endeavor, including aerospace engineering, biomedical engineering, chemistry, chemical engineering, computer science, electrical engineering, electronics engineering, systems engineering, material sciences, and mechanical engineering. These technical backgrounds, coupled with the scope and depth of our experience as corporate and private legal counsel provide a strong foundation for representation in all aspects of intellectual property, including: patent, trademark, and copyright procurement; patentability, registrability, validity, clearance and infringement opinions; licensing, confidentiality and employment agreements; due diligence investigations and technology related employment matters; and IP aspects of M&A and equity investments, acquisitions, and divestitures, technology transfers, development agreements, joint ventures, and strategic alliances and research agreements and framework agreements.
