I am an attorney licensed to practice in Texas, Louisiana and before the United States Patent and Trademark Office. Laws vary from jurisdiction to jurisdiction and the above may not be an accurate assessment of the laws for your area. The above should be taken as general guidance and not specific legal advice. For specific legal advice you should seek a licensed attorney in your jurisdiction practicing in the area specific to your issue. The above does not constitute or establish an attorney client relationship. If you wish to receive specific advice about your legal issue, then contact my office to schedule a personal consultation.
