“In patent law it is important to be able to focus on the nuances of an issue while still remaining cognizant of the big picture, and to think creatively when analyzing technical subjects.”

Selected as an Emerging Lawyer in Intellectual Property Law, Leading Lawyers Network (2015 and 2016)

Mark Borsos has a particularly broad spectrum of skills to assist clients of various sizes with all facets of intellectual property. His experience includes patent litigation, patent prosecution, freedom-to-operate analysis, post-grant patent proceedings (including reissue, reexamination, and inter partes review proceedings), trademark litigation, trademark prosecution, trade secret litigation, copyright litigation, arbitration, and mediation.

Mark’s experience in strategic patent portfolio creation and management complements his comprehensive patent litigation experience in discovery, summary judgment briefing, pretrial preparation, settlement negotiations, and trial work as a member of both large and small litigation teams. Mark is also skilled at employing reissue, reexam, and other post-grant mechanisms to advance licensing and litigation objectives, both offensively and defensively.

Mark’s patent prosecution, litigation, and freedom-to-operate analysis extends to a wide array of technical fields, including, among others:

  • Medical devices and therapies
  • Biotechnology and gene therapy
  • Security systems and device encryption
  • Construction and building products
  • Chemistry and polymer technology
  • Food products, processing, and packaging
  • Printers and ink cartridges
  • Semiconductors and fabrication
  • Inventory management systems
  • Irradiation chambers
  • Lighting technology
  • Protective and athletic garments
  • Automobile parts and accessories

Mark also has broad experience in trademark and copyright protection and enforcement. Mark has experience both in defending clients accused of infringement and in enforcing clients’ trademark and trade dress rights, and assists clients in trademark prosecution, freedom-to-operate analysis, litigation, and licensing. He counsels trademark clients from a holistic viewpoint in order to help clients to understand not only the extent of their rights, but also the importance of specific trademark assets to their overall branding strategy. Likewise, Mark has helped both copyright holders and accused infringers to understand and protect their rights in a wide variety of circumstances.

In all situations, Mark seeks to help clients develop strong positions with respect to intellectual property while also making sure that the scope and cost of legal representation makes sense in view of the client’s long-term goals.
