Filing patents or trademarks in other countries requires hiring a local patent or trademark attorney in the other country (or in some cases an attorney in one country can assist with filing in multiple countries).


Most countries require that a first patent application be on file before the invention is publicly disclosed or sold, so typically (for US based applicants), a US patent application is filed first.  Then, before the expiration of 6 months (for design patents) or 1 year (for utility (invention)) patents, the foreign application must be filed and priority is claimed from the first filed patent so that disclosure or sales after your first filing does not act to bar filing in the other country. 

We have an established network of attorneys in other countries that we use, many of them personally known to us.
