Fred Wilf

Fred Wilf is the founder and managing partner of Wilftek. He has been helping his clients succeed for over 30 years.

Fred was fascinated by the technology zeitgeist while in college, and worked briefly as a programmer to pay for law school. Fred understood early on that as it became less expensive and more powerful, information technology would be an ever-growing component of each person’s life, and eventually technology would empower virtually all businesses.

After graduating law school, Fred began his law career as a technology lawyer, at a time when very few attorneys practiced technology law, and even fewer practiced technology law outside of Silicon Valley. Fred was grateful to be mentored by pioneering technology attorneys, and in the three decades since then, Fred has been paying it forward by mentoring and training attorneys to practice technology law. Fred continues to mentor attorneys, entrepreneurs and other business people at the intersection of technology, intellectual property and business.

In addition to information technology, Fred works with other technologies across multiple industries, including healthcare, chemicals, electronics, and business services. His work covers the entire lifecycle of a technology, from initial idea, through development, bringing it to market, commercialization, and then sale or sunset (often in favor of a newer technology). From strategy to implementation, Fred partners with his clients to achieve the results they seek.

Wilftek is a boutique law firm, but Fred has also worked with a large regional firm (Saul Ewing) and an international law firm (Morgan, Lewis & Bockius). Fred has also briefly worked in-house with a chemical company and with a telecommunications company.

In addition to his transactional work, Fred serves as an arbitrator of disputes involving business, technology and intellectual property issues, mostly through the American Arbitration Association and the International Centre for Dispute Resolution. Serving as an arbitrator provides an additional dimension to his transactional work, as it helps him and his clients build better business and legal relationships at the outset.

For publisher Thomson Reuters West, Fred edited and contributed to a four-volume treatise entitled Computer Software, which was originally written by L.J. Kutten. Fred has volunteered with the American Bar Association, the Philadelphia Bar Association, and Pennsylvania Bar Institute. In addition to early continuing legal education (CLE) seminars on telecommunications and the law, Fred organized and ran CLE and other seminars on Internet law issues for over 20 years. More recently, Fred has spoken on blockchain and NFTs. He also works with charities and non-profits, and provides services pro bono publico.

Fred has received recognition for his work:

  • Martindale-Hubbell AV Preeminent® Peer Review Rated awarded in accordance with the Martindale-Hubbell certification procedures, standards and policies at
  • Best Lawyers® recognition for Information Technology Law (2011-Present)
  • Volunteer of the Year honored by Philadelphia Volunteer Lawyers for the Arts (2007). One of two volunteers honored that year.
  • Milton Schwartz Award by the Independent Computer Consultants Association (ICCA) “for outstanding legal contributions to the computer consulting industry and to the Association” (2001).

Fred is a member of the Pennsylvania and New Jersey Bars, as well as the Bars of several federal courts.
