Daniel N. Calder
Professional Experience

Dan focuses on patent prosecution and procurement, due diligence, intellectual property opinions, and trademark prosecution and procurement.

Client Work

Dan works primarily in securing patents for clients in the fields of storage area networks, wireless communications, computer processors, semiconductors, industrial mechanics and business methods.  This includes patent prosecution and patent counseling (e.g., non-infringement or “right-to-use” opinions and patentability opinions). Dan also engages in trademark and copyright matters, as well as litigation involving all areas of intellectual property law.

Dan has counseled clients on patent, trademark and copyright matters during his entire career. His experience both as an in-house patent attorney and a private practice attorney provides Dan a unique perspective from both the legal and business stand-point.

In counseling clients, Dan prepares validity and infringement studies to assist clients in evaluating their patent portfolios. Dan guides clients toward decisions concerning the direction of future patent protection, the need for licensing-in technology or cross-licensing technology, as well as the potential outcome of intellectual property litigation.

Dan has shown the talent and capability of providing a client with the knowledge to effectively resolve a full gamut of intellectual property related issues.

Previous Work

Dan has worked exclusively in the field of intellectual property for over 35 years. His experiences include in-house patent counsel for several Fortune 500 Companies, and private practice representation of small, medium, and large domestic and international corporations. Dan has extensive experience in patent prosecution and patent litigation. During his career, he established a strong patent portfolio built on pioneering solar cell technology for one of the worlds preeminent electronic technology corporations, and worked with a team that successfully asserted patents to preserve the corporation’s exclusive market position. The patent portfolio based on the pioneering solar cell technology was eventually sold along with the related business for over fifty million dollars.

Dan prepared infringement validity opinions directed to adverse patents that avoided litigation or led to a favorable licensing or business arrangements. While in-house counsel for a major retail chain, Dan managed infringement claims based on the company’s sale of suppliers’ products and asserted indemnification rights that avoided liability. He developed and implemented a licensing plan for the production and sale of a product line unrelated to the company’s primary business. Dan also worked with product design and development teams to develop products which avoided infringement of competitors’ patents.

Dan has experience managing patent, trademark and copyright infringement cases. His litigation experience includes a variety of technological fields from electronic and semiconductors to mechanical devices used in the steel industry. Dan also negotiated and drafted license agreements with guaranteed minimum royalties for medium-size clients which avoided litigation with larger corporations.

While working in private practice, Dan was given the responsibility to prosecute patent applications for a multi-national Japanese electronics corporation. Dan expanded the prosecution of applications for that client dramatically over a three year period, from 160 application per year to nearly more than 400.

Dan received several certificates of accommodation from the American Bar Association for his leadership with the Membership Committee of the Intellectual Property Section, and as a member of the Annual Review Board and as Deputy Chairmen of the Annual Review Board which has published the Annual Review of Intellectual Property Law Developments since 2006.

He was selected for inclusion in Pennsylvania Super Lawyers®, published by Thomson Reuters, from 2013-2014.

Life Beyond the Law

I enjoy being on the ocean either fishing or boating. I’m also an avid amateur photographer, and relax as an archer shooting at paper targets. But my greatest joy is playing with my grandchildren.
