About David E
David E Blau trained first as a scientist and later as a lawyer. He earned a B.S. in mathematics and computer science from the California Institute of Technology in 1998. He returned to the classroom a few years later and completed his J.D. at Chicago-Kent College of Law in 2007. Those two degrees shape his approach to practice: technical problems get parsed like proofs, and legal questions get translated into practical steps.
After law school he moved into intellectual property work. His technical background made patent prosecution a natural fit. Over time he developed experience preparing and prosecuting patent applications and advising clients on patentability and portfolio management. He also took on trademark matters and other aspects of IP counseling that frequently arise alongside patent work.
He is admitted to practice in Massachusetts and is registered to practice before the U.S. Patent and Trademark Office. That combination allows him to handle both state-level legal issues and the federal mechanics of obtaining patents. In client meetings he often acts as a bridge between inventors and examiners, helping inventors frame technical descriptions in legal terms that the patent office can act on.
At Daly Crowley Mofford & Durkee LLP he works with a range of clients, from individual inventors to small and mid-sized technology firms. His day-to-day work includes drafting patent applications, responding to office actions, conducting prior art searches, and preparing opinions on patentability and freedom-to-operate. He also counsels clients on trade secret protection and trademark filing strategies when those issues intersect with patent matters.
Colleagues describe him as methodical in his drafting and direct in his client communication. He prefers careful claim construction and clear technical descriptions over ornate language. That preference reflects his training in both mathematics and computer science. It also reflects a practical sense of how patent prosecution unfolds, where clarity often shortens the path to allowance.
He publishes and speaks sparingly, choosing projects that tie directly to client needs rather than broad legal commentary. Outside the office he follows developments in software and hardware innovation closely, often testing new tools that might affect claim drafting or patent searching. He focuses his current practice on patent prosecution, counseling on patentability and freedom-to-operate issues, and related trademark and trade secret matters for clients in software, hardware, and engineering sectors.
