There are currently 120 national patent systems throughout the world, each challenging inventors with opposing philosophies and examination rules. It’s easy to spend upwards of $250,000 for patent filings and legal fees in key countries.
The creation of a single global patent system could solve this conundrum for small inventors. Even multinational corporations that can afford to file everywhere are pushing for “deep harmonization,”
an international initiative aimed at forging a global patent. But in return for eliminating duplicate filing fees, most issuance costs, and translation requirements, such an effort will likely entail stark trade-offs for innovators worldwide.
