Klein & Wilson attorneys have the broad experience and trial skill to bring appropriate legal malpractice actions against even the largest law firms in the country.

– Shareholder Disputes

In closely held corporations, shareholder disputes are common. Most of these disputes can be resolved among the shareholders with little, if any, assistance by attorneys. Our firm has experience litigating corporate disputes against small and large companies, including bringing derivative actions when necessary.

– Unfair Competition and Trade Secrets

A company’s success is often tied to its ability to protect its intellectual capital in today’s modern world of trade and commerce. Our attorneys are committed to helping clients pursue and defend claims of trade secret theft and unfair competition.

– Intellectual Property

Our lawyers have extensive experience in intellectual property litigation and business litigation matters. Their lawyers can assist clients with: copyright infringement; unfair competition; trade secrets litigation; trademark infringement and dilution; allegations of trademark misappropriation; and trade dress and trademark disputes.

– Insurance Bad Faith

Insurance disputes are a highly complex area of the law which requires the attention of an experienced attorney. We are seasoned trial lawyers who have handled a wide range of complex insurance matters. Business litigators must be familiar with opportunities to obtain insurance coverage for their clients.
