Bayuegua provides an intellectual-property research platform for enterprises, universities, research institutions, and IP agencies. Its former Innovation Brain platform has been upgraded into the Qingce product range. The software combines patent and trademark search, research workspaces, AI reading and drafting assistance, analytical reports, and data APIs. Teams can investigate related inventions, organize documents, and prepare material for professional review. These tools support research and drafting; they do not establish patentability or guarantee freedom from infringement.

Search related inventions and compare technical approaches before starting or refining a research project.
Use AI drafting support to structure a technical proposal, then have an IP professional review it before filing.
Use saved queries and research folders to collect relevant patents and compare applicants or patent families.
Use purchased API access to bring selected patent and legal-status fields into an organization's intelligence workflow.
The offering supports SaaS subscriptions, API packages, and private deployment, with configurations tailored to team size and use. Trial and demonstration requests are available; they do not imply unrestricted free access.
Discuss requirements, assess the integration, and purchase a product package. Then obtain an API key, use the documentation, and test calls before production use. Call counts and usage details are available.

No. Check search coverage, cited documents, translations, and draft claims with a qualified IP professional before filing or relying on them. A similarity result is not a legal opinion or proof that a patent will be granted.
