  • “Jai-wei Gan was hired to conduct a validity search for us. I was very impressed with her thorough and detailed search. The results of her search included obscure foreign patent references and non-patent literature that were very helpful. I would strongly recommend Jai-wei Gan to other patent practitioners, law firms, and companies.”
