Patent & Utility Model Filing
I was confident in my technology, but completely lost when it came to patents. Willaw proposed a patent structure connected to our investment strategy. They genuinely understand the founder’s perspective. I’m truly grateful.

International Filing
As we prepared our global SaaS service, international filing was essential. And Willaw IP handled everything from PCT to country-specific entry strategies with a highly organized approach. Their coordination with overseas law firms was seamless!

Trademark & Design Filing
We filed our trademarks while launching our brand. What impressed me was that Attorneys at Willaw IP didn’t stop at simple registration. They considered future brand expansion and built a strategy around it. Incredibly reassuring.
