PatSnap, a Euro-Asian company that offers a patent and R&D platform and services, has pulled in a $38 million Series D funding round led by existing investors Sequoia and Shunwei Capital, the investment firm founded by Xiaomi co-founder and CEO Lei Jun. Southeast Asia’s Qualgro also took part.

All three backed the company in 2016 when it led an undisclosed Series C round. While PatSnap didn’t give a figure for that previous round, it is saying this time around that it has raised over $100 million to date. Doing some quick via math via figures on Crunchbase suggests that the Series C was something in the region of $50 million.
