Patents are immensely valuable tools for protecting and commercializing inventions.  A patent grants the patent owner the right to exclude others from making, using, selling, and offering to sell the patented invention for the term of the patent.

Our experienced patent attorneys are skilled in preparing and prosecuting patent applications covering a diverse range of complex technologies.  Our clients’ inventions include innovations in the areas of mechanical, electrical, computer, software, biotechnology, life sciences, chemical, business methods, and design arts.

Our patent lawyers routinely prepare provisional and non-provisional utility patent applications, design patent applications, and plant patent applications for filing with the United States Patent and Trademark Office (USPTO).  Once on file with the USPTO, we vigorously negotiate with patent examiners to obtain the best patent coverage possible for our clients.  Additionally, we advise clients about foreign patent protection and work to protect their inventions with patent applications in countries all over the world.

We use our legal and technical expertise and experience to advise clients regarding the relevant patent laws and how to most effectively protect their inventions.  Our knowledge of patent law and examining procedures makes us exceptionally qualified to advise clients in forming a patent filing strategy.


Our firm often recommends prior art searches for our inventor clients, and we offer efficient services for locating and analyzing patents, published patent applications, and other prior art references as they relate to the patentability of an invention and/or patent infringement concerns.  Prior art searches provide clients with added information about potential competitors and/or risks associated with related technologies that are patented, patent-pending, or in the public domain.

Further, we have significant expertise in providing detailed analysis of prior art and formal patentability opinions regarding the outlook for obtaining a patent on a particular invention.  Patentability opinions frequently help clients make informed business decisions that best position their business.

Our patent lawyers routinely perform thorough patent infringement analysis and prepare formal freedom-to-operate, or infringement, opinions for clients.  These opinions identify potential risks of patent infringement of issued patents owned by other parties, and they provide detailed analysis of closely-related patents.
