Consulting Concerning the Patents of the Lighting Electronics Industry
Peter W. Shackle Ph.D.
Dr. Shackle has 30 years of experience related to power electronics and the lighting industry. With 61 issued US patents in this field and a doctorate from the prestigious University of Cambridge in the UK, he is well positioned to write declarations concerning patents concerned with LED lighting and lighting electronics in general. Dr. Shackle is an elected senior member of the IEEE and a member of the illuminating engineering society. He is very familiar with Philips patents concerning lighting electronics.
Dr. Shackle has been involved in nine patent disputes, involving both patent holders and petitioners in IPR ( Inter Partes review) proceedings. He has also been an expert witness in district court cases, and has appeared as an expert witness in proceedings at the International Trade Commission (ITC) court in Washington. He has cumulatively given four days of deposition testimony as an expert witness in support of legal declarartions.and has also appeared as a witness for a case involving a patent which he authored. See the publications section of this website for examples.
Dr. Shackle has been a speaker at the Strategies in Light meeting and has authored articles on LED circuits in LEDs magazine and LED Professional magazine. (see publications section of this web page)
Dr. Shackle is available to help Lighting Electronics companies draft patent disclosures ready for an attorney to work on, and with his wide experience in writing patents he can be especially helpful in drafting the most powerful claims possible in view of the technological background in the industry for the patenting of some new product. He is well qualified to perceive infringement of patent claims upon other existing patents. He is experienced with issues of LED chromaticity and analysing industry patents for the purpose of claim construction.
One of Dr. Shackle's recent inventions has been the invention of an AC LED module of a kind which has higher efficiency than other AC LED modules, and which also has the capability to be scaled up to indefinitely large sizes, unlike all other such circuits which have a power limitation. See the "What is Photalume AC LED Technology about?" section of this website for technical and licensing information. His experience particularly covers triac dimming of LED circuits.
