David D. Murray, a graduate of The University of Michigan College of Engineering (Mechanical Engineering) in 1970 and the University of Toledo College of Law (Juris Doctor) in 1977, passed the Ohio Bar exam and the Patent Office registration examination in the fall of 1977.  Since then, he has limited his private practice to various aspects of intellectual property law with an emphasis on patent prosecution, counseling, litigation and teaching.  He has prepared and prosecuted several hundred patent applications, a number through appeal and allowance.  He has litigated both patent and trademark matters as plaintiff’s and defendant’s counsel.  He has been an expert witness in several federal court actions, appointed a Special Master and taught substantive Patent Law, Patent Prosecution and Copyright courses since 1994.

Mr. Murray has been engaged in the private practice of intellectual property law beginning in 1976 in Toledo, Ohio and in Ann Arbor, Michigan beginning in 2000.  He has extensive patent preparation and prosecution experience with automotive powertrain components, especially transmissions and transfer cases, and mechanical, electromechanical and electrical controls, devices and systems.  The relatively broad subject matter of his practice is partially the result of commencing his undergraduate study in electrical engineering and concluding it in mechanical engineering.

Additionally, Mr. Murray  devotes significant time to trademark counseling, acquisition before the USPTO and inter partes matters and lesser time to copyright and trade secret matters.

In 2000, Mr. Murray received the AV rating from Martindale-Hubbell.  This rating resulted from a confidential survey of his peers in the legal profession in Toledo, Ohio.

Mr. Murray has been active as both plaintiff’s and defendant’s counsel in patent and trademark litigation.  More recently, he has been an expert witness in several patent and trademark matters.  He has been appointed twice as a Special Master by Judge Avern L. Cohn in patent litigation pending before his court in Detroit, Michigan.

In the fall of 1994, Mr. Murray was appointed the Adjunct Professor of Patent Law at the University of Toledo College of Law.  He has taught courses in substantive Patent Law, Patent Prosecution, Copyright Law and an Intellectual Property Law Survey course (Patents, Trademarks and Copyrights).  He developed, received faculty approval for and teaches the first Patent Prosecution course offered at the College of Law.  Mr. Murray has been teaching at the College for over twenty years.

From the fall of  2002 until the spring of  2004, Mr. Murray also taught at the Ave Maria School of Law in Ann Arbor.  Again, he taught a substantive Patent Law course as well as an Intellectual Property Survey course.
