SERVICE
🔬 Patent Filing Service
Protecting your invention with strong, defensible rights
Patent rights, designed by attorneys who understand your technology.
Our technical-background patent attorneys support you from R&D to commercialization.
What Is a Patent Right — A 20-Year Exclusive Right
A patent right gives you the exclusive right to practice a new invention (a technical idea). For up to 20 years from the filing date, you can exclude unauthorized use by third parties — making it one of the most powerful intellectual property rights for establishing competitive advantage.
Benefits of Holding a Patent
Why Choose EVORIX
🎯 1. Deep Technical Understanding
Our attorneys have backgrounds in mechanical, electrical, software, chemical, and biological fields. Through dialogue with inventors we go beyond surface structure to identify why the invention is superior and where the inventive step truly lies — and design strong claims around that core.
🔍 2. Thorough Prior Art Searches
Pre-filing prior art searches assess registrability. Our attorneys, well-versed in JPO examination practice, identify differentiation points against similar technologies — avoiding wasted filings while improving your odds of grant.
📝 3. High-Quality Specification Drafting
A patent specification is not merely a technical document — it is a 20-year contract for asserting rights. We draft with future business expansion and litigation in mind, securing broad and enforceable claim scope.
