While the financial details have not been revealed, Google has confirmed the deal covers a broad range of products and represents a long-term agreement.
The deal also led to both companies collaborating on future technology developments. The California-based internet giant has similar partnerships with Samsung, LG and Cisco Systems, but this is the first with a large Chinese tech firm. Many of its products, such as its search engine, app store and Gmail service, are now blocked in mainland China.
"By working together on agreements such as this, tech companies can focus on building better products and services for their users", said Mike Lee, Google's head of patents.
For Google, the agreement represents further headway into China without relying on the banned Google Search.
Over the past year Google has increased its presence in China, launching an AI lab in Beijing and introducing a new version of its translation app.
Earlier in January, Google's venture firm capital invested into Chinese living streaming company, Chushou.
Tencent, which is valued at more than $500 billion, per one report, operates WeChat, a messaging platform, and QQ, China's leading social media and gaming network.
Google moving into the Chinese market?
Google announced it reached a cross-licensing agreement with Chinese tech giant Tencent.
It is unclear whether Tencent will now also have access to some of Google's patents but it would not surprise us if this was the case. The Chinese firm made numerous deals previous year, including investments in Snap and Tesla.
