Filing patents internationally can enhance valuation and status, but it is an expensive, complicated process as patent laws and procedures vary globally. There is no single international patent - applications must be filed in each country separately. Indians have 12 months from domestic filing to file abroad. The PCT and convention routes allow filing in multiple countries simultaneously, but require meeting individual country deadlines. Key factors for considering international filing include future business plans, a technology's market potential, and budget to handle long timelines and high costs of foreign prosecution and maintenance. International filing decisions require weighing these pros and cons based on business goals.
