I started a company making aprons. I named the company after myself. I submitted a trademark application. I recently received a certified letter from Chanel, Inc., stating that I am infringing on their trademark and basically asked me to stop using my name, withdraw my application and never try to use the name again. I use my first name (which has an additional "l" at the end) and last name and the artwork I use as my logo resembles a sketch of a woman in a vintage apron. Is this something that they automatically send out and what are my options. Not sure if this matters, but the name I use is my birth name. Any advice or guidance will be greatly appreciated.
