Can an individual appeal there own case write a letter to court on a patent?

We have a patent number and we have been trying to get the utility patent but we keep getting rejected the lawyer wants 1800 to file an appeal and chances are we might not get it can we just appeal the case ourselves and write the letter to judge
in louisiana if we are in ca thank you Dawn Marie

You could file a Revocation of Power of Attorney and file the appeal yourself. However, an Appeal Brief is a very formal documents with a lot of very specific requirements. If you don't prepare it correctly, it will be rejected.

Also, you seem confused about where to send it. If you are still trying to get the patent then the place to send it is the Board of Patent Appeals and Interferences at the U.S. Patent and Trademark Office, unless you have already done that and are now considering an appeal to the federal circuit. If thats what you're doing, you really need the help of an attorney.

In either case,1800 is cheap.

If the invention isn't going to make you 1800, maybe you should rethink how important the patent is to the business...

Have you looked at the documents being cited against your claims? Do they really not disclose or suggest your invention?

an idividual can indeed appeal, but an appeal does not consist of writing a letter to a judge. If you don't know what is involved in an appeal, don't even try it.
