In the information age in which we live, a key factor affecting a company’s valuation is the degree to which it effectively develops intellectual property.  Intellectual Property (“IP”) consists primarily of trademarks, copyrights, patents, trade dress, and trade secrets.
Intellectual property is recognized as the most important asset of many of the world’s largest companies, and it is often the foundation of market dominance and profitability. It has been estimated that in 1975, tangible assets represented more than 80% of U.S. corporate value in the S&P® 500 whereas IP comprised less than 20%. Today, the ratio has inverted. Now more than 80% of U.S. corporate value is in IP.
According to new research, more than 74% of brands experience trademark infringement each year. As more companies seek to develop and protect IP, trademark infringements, copyright infringements, and patent infringements are becoming more common. Frequently infringement issues begin with a trademark or copyright cease and desist letter which we handle on a daily basis.  We are also a top intellectual property law firm with respect to trademark, copyright and patent infringements on Amazon, and Trademark Trial and Appeal Board matters including Trademark Opposition and Trademark Cancellation.  You can see the over 350 TTAB cases that we have handled here.  We are also highly experienced with intellectual property lawsuits in federal court.  In the event of an infringement, we aggressively pursue and defend our client’s rights.  To learn more about our litigation services, please see our trademark litigation, copyright litigation, and patent litigation pages.
On the transactional side, we have filed and registered over 1000 trademark, copyright, and patent applications for our clients in the U.S. and worldwide.  If you are seeking the best IP law firm in southern California, please contact us.  Please complete a contact form for the fastest response.  We look forward to assisting you.
