Are there multiple “atezolizumab companies” depending on the question?

Yes—search results often show different entities depending on whether you mean:
- the marketing/brand owner (Genentech),
- the parent company (Roche),
- the specific manufacturer of clinical supplies in older trials,
- or the company challenging or litigating related patents.

If you tell me what you mean by “company” (maker/brand owner, manufacturer, or patent holder), I can narrow it to the exact entity.
