Alex Patchen has extensive experience representing clients ranging from entrepreneurs and small business to Fortune 500 companies in complex commercial litigation and arbitration matters.  He represents clients in all phases of complex commercial litigations in federal and state courts as well as arbitral proceedings.  He counsels clients from numerous industries including software companies, financial institutions, pharmaceutical companies, media companies, and consumer manufacturers on diverse array of disputes including breach of contract, licensing disputes, bankruptcy and employment discrimination.   

His litigation expertise covers a range of intellectual property disputes as well. He has represented clients to enforce their patent rights.  He has represented owners of television programs in enforcing their copyrights and trademarks against pirates distributing the programs over the internet. He has successfully obtained a permanent injunction on behalf of two technology companies for misappropriation of their respective trade secrets.  He successfully defended a licensor from a dispute from a patent licensee seeking millions in royalties.

Mr. Patchen believes the best way to fully represent a client is to obtain a deep understanding of the client’s business and how a specific dispute impacts the business as a whole.  The trusting relationships that develop allow him to develop efficient and pragmatic strategies that are tailored to address both the legal and business concerns driving each individual dispute.  Through taking this approach, where appropriate, he recommends alternative dispute resolution, including arbitration and mediation, as a way to properly resolve a dispute.

Beyond his litigation experience, Mr. Patchen has also represented the Trustee for the SIPA Liquidations of Lehman Brothers Inc. and MF Global Inc.  In that role, he was responsible for the analysis, reconciliation, and close out of thousands of complex financial transactions that were open on each of the entities respective filing date.
