Donald M. Cislo (emeritus) and Charles H. Thomas (emeritus) started the firm in 1979.  Daniel M. Cislo joined the firm in 1987 and for the last fifteen years has been the managing partner of the AV rated intellectual property law firm of Cislo & Thomas LLP.  The AV rating is the highest rating that can be achieved by the revered Martindale Hubble rating system.  The Bar Register of Preeminent Lawyers lists the firm in the top 5% of all law firms in the country.  Although we are best known for our patent and copyright work, we were recently named in the Top 50 Trademark Attorneys by Trademark Insider's 2006 Annual Report.  We serve all aspects of our clients' needs for intellectual property services involving patent, trademark, copyright, domain name, trade secret, and trade dress rights.  This includes searching, clearance, prosecution, licensing, maintaining, and enforcement of intellectual property rights.    

Daniel M. Cislo splits his time overseeing the Westlake Village, Santa Monica, and Santa Barbara offices where the firm's attorneys and paralegals provide the highest quality of intellectual property service using its proprietary Quality Client Care® or QCC® approach.

The firm uses a series of weekly meetings where all attorneys, paralegals and staff look at the past week's performance and evaluate how better to serve our clients, improve the efficiency of the services we deliver and ever improve the quality of service provided.  The paramount question we ask each week is "How can we provide the greatest quality of service to our clients at the most reasonable of costs considering the client's objectives?"

The firm believes that to serve its clients in Southern California, it must provide attorneys that are first engineers and scientists admitted to the United States Patent Office and be available to meet with our clients to fully understand our client's objectives and technology.  In addition, they must have real world experience in business and litigating intellectual property matters before the U.S. Patent and Trademark Office, as well as in the Federal and State Courts. 

This is one reason we have offices throughout Southern California, namely Santa Monica, Westlake Village and Santa Barbara, California so that we can be easily available to meet with our clients to come up with solutions to not only address their intellectual property needs, but also enhance their business and continue to help them grow.  We have been doing this successfully for almost thirty years.  Just ask our clients.
