Although Chiari malformation may be present with no symptoms at all, this crowding can cause a backup of spinal fluid in the spinal canal which often results in problems which may or may not change in the adult such as: Sub-occipital pressure headache, especially when coughing, sneezing or straining.
Patent applications involve lots of text and drawings, even for simpler inventions. The first step in the patent application process is to file a non provisional patent application, which involves paying attorney fees in the range of $5000 to $15,000 or more, depending on the intricacies of the invention. The amount you spend on a patent application will also depend on the market opportunities.
The costs can add up quickly no doubt, and there will be post-filing costs once the Patent Examiner starts to examine the application filed, but those will be the subject of a future article. Still, you should budget at least another $5,000 to $7,500 for prosecution and issue fees to the Patent Office.
