What is patent annuity and why is it important?

Patent annuity (also called patent maintenance fee or patent renewal fee) is a periodic fee that patent holders must pay to keep their patents in force. Missing an annuity deadline can result in the patent lapsing and losing protection. Kangxin's Patent Annuity service provides smart reminders and automated tracking to prevent missed deadlines.

How many countries does the patent annuity service cover?

Kangxin's Patent Annuity service covers patents in 100+ countries and regions worldwide, including major jurisdictions such as China, the United States, Europe (EPO and national patents), Japan, South Korea, India, Australia, Canada, and many more.

How does the smart deadline reminder system work?

The platform automatically calculates upcoming annuity deadlines for all patents in your portfolio and sends email and in-platform notifications at customizable intervals (e.g., 90 days, 60 days, 30 days before due date). This ensures you never miss a critical payment deadline.

Can I look up official patent fees on the platform?

Yes. The platform includes an Official Fee Search tool that allows you to look up patent annuity fees for different countries, patent types, and annuity years. Fee data is regularly updated to reflect the latest official schedules.

Does the service support multi-currency payments?

Yes. Official patent annuity fees in local currencies are automatically converted and settled in EUR or USD. Fees are displayed in the local official currency alongside the EUR/USD equivalent, with transparent exchange rates and no hidden conversion fees.

How secure is the patent annuity payment process?

Kangxin's platform is certified with ISO 27001 (Information Security Management), ISO 27017 (Cloud Service Security), ISO 27701 (Privacy Information Management), and China Information Security Level 3 Protection. All data is encrypted in transit and at rest.
