Alteogen vedolizumab patent?

Do you want me to look up whether Alteogen has any patents related to vedolizumab (e.g., production methods, glycoengineering, biosimilar claims, etc.) and summarize the patent family, status, and expiry? If yes, please specify:

- Which jurisdictions to search (US, Europe, Korea, China, World/WIPO, etc., or worldwide).
- Whether you want granted patents only or including pending applications.

I can then pull publicly available data from patent databases (Google Patents, Espacenet, USPTO/WIPO/KIPO) and give you a concise report with publication numbers, assignees, status, and potential freedom-to-operate considerations.

If you’d prefer, I can also start with a quick background on vedolizumab and Alteogen’s involvement before diving into patent details.
