Additional Experience

Expert Witness Experience
Litigation Consulting Examples:
1. Prepare Expert Report on six technical questions regarding processes and sequence of steps to build a polysilicon plant, describe load adjustment operations and individual commissioning of equipment, describe impact of hydrogen purity on polysilicon production, review and comment on hydrogen purity levels achieved in plant operation, and opine on safety and accepted engineering practices at the polysilicon plant. Prepare a Responsive Expert Report detailing errors and false assumptions in claimant's expert report. Testify on these reports before an international tribunal.
2. Review and comment on Albemarle patents, critical review of Albemarle support deposition, prepare deposition in the case, give a videotaped deposition and attend court proceedings as an expert witness. The technical report included analysis of fluid bed reactor deposition of granular polysilicon production, material qualification (fitness for use), technology for single crystal ingot production using granular polysilicon, evaluation methods for single crystal silicon ingots, Albemarle specifications for granular polysilicon, customer problems with granular polysilicon, and MEMC patents.
3. Report and testimony including detailed information on the polysilicon industry, industry demand and supply shortage, value of polysilicon in 2005, review and analysis of polysilicon specifications, review of purchase orders and opinions on the case.
4. Review of Japanese patent, a technical report on silane purity, silane market, impurity effects, purification methods, Japanese suppliers of silane, and review of twelve literature references.
5. Prepare review on silane production, components, safety risks, maintenance and safety process management, piping corrosion and risk mitigation practices.
6. Technical evaluation of Semiconductor Energy Lab (SEL) patent claims, critical evaluation of SEL supporting data for the case, written testimony and videotaped deposition for court. The technical evaluation included the production of silane (SiH4), purity, quality assurance methods, silicon film deposition methods, and specifications.
