|Expert Witness Experience|
| Expert has worked with legal firms on three different cases. He is experienced in giving depositions, working with lawyers and dealing with legal documents.
Expert is recognized worldwide for his knowledge and expertise in catalyst preparation, design, catalyst deactivation & regeneration, and process design/performance. He has substantial experience as a technical expert on litigation relating to catalyst failure, catalyst performance, plant performance and safety, causes of catalyst deactiva-tion, and catalyst regeneration processes. Several examples of his legal activities, experience, and expertise are summarized below (without dates and company names):
1. Expert witness for defendant in the failure of a catalytic converter for a diesel engine in a sewage treatment plant: reviewed discovered materials and patents; determined causes of failure; provided expert advice to the defense counsel, and gave a 6 hour deposition to the plaintiff’s lawyers. Litigation was settled out of court in favor of the client.
2. Expert witness for the defendant on litigation involving the failure of a catalytic converter for a wood stove: reviewed patents, & legal materials; provided expert advice to the defense counsel, wrote a technical report in support of the defendant, and delivered a deposition. The case was settled out of court in favor of the client.
3. Expert witness for the plaintiff, an engineer permanently injured by exposure to flue gas in a power plant; assist-ed counsel for plaintiff in searching literature on health effects of power plant pollutants and providing written testimony on effects of acute exposure to SO2 and NO. Litigation was settled by arbitration in favor of client.
4. Expert was sued by a California company because of an accident causing permanent shut-down of an NF3 plant in Nevada for which BCS and the BCS design team had provided preliminary design services. BCS had provided a comprehensive report with detailed recommendations regarding safety and location (“not to be built in a populated area”) which were not followed by the plaintiff in the operation of their plant. As a result the plant was permanently closed after city officials ruled it to be a serious hazard to the citizens of the town. Expert worked closely with local and Calif. counsel to successfully quash this complaint.
5. Called as an expert witness to give deposition for plaintiff and defendant in a suit brought against the State of Nevada by the same California company described in No. 4. No information was provided to the consultant regarding the outcome of this case.
6. Technical expert for the plaintiff, a company (A) engaged in regeneration of catalysts for reduction of nitrogen oxides in power plants, who sued a new competing company (B) established by former employees in the same county for practicing trade secrets stolen from the parent company. Expert assisted the counsel for the plaintiff by reviewing relevant patents & operating procedures used by both companies and court documents for the defense, and provided written testimony of his conclusions and recommendations.
7. Technical expert for the defendant, a relatively small company engaged in biodiesel manufacturing that was sued for patent infringement by a large biodiesel manufacturer. Expert assisted the counsel for the defendant by reviewing the relevant patents for both companies and providing a technical assessment regarding the pros and cons of the suit and patents.
