He has extensive experience in complex and commercial litigation, ranging from insurance recovery disputes to trade secrets issues, and has significant experience in assisting foreign aerospace companies with international arbitration disputes with first-tier aircraft manufacturers.

Earlier in his career, Chris represented large public companies in mergers, acquisitions, strategic investments and private financings; private companies in initial public offerings; and emerging growth companies in general corporate matters. Chris' transactional experience also offers clients a unique perspective on risk mitigation strategies to avoid costly litigation in the future.

Kristopher R. Wood Senior Associate

Orange County

Mr. Wood's experience spans multiple industries, practice areas, and jurisdictions. Through his work, Mr. Wood has developed a strong sense of the importance of each client's unique industry and circumstances to the matters he undertakes, and he thoroughly enjoys each chance to learn about his clients and their work. Although Mr. Wood's focus is on trade secret misappropriation and business torts, he prizes variety in his practice and relishes the chance to take on new challenges in different areas of law.

Mr. Wood is known for developing a deep understanding of the facts and law in each case. In most of his cases, he serves as the point person for fact discovery, and through this experience he has created highly efficient and effective methods of identifying, tracking, organizing and synthesizing key facts in even the most complex matters.

Mr. Wood's interest in efficiency extends beyond the specific matters he works on. Mr. Wood enjoys identifying tasks in his practice that can be automated and developing tools to do so. This redounds to his clients' benefit--in one case Mr. Wood's automation tool led to nearly a 50% reduction in the total time required for a given matter.
