Patent calculators — fees and deadlines

The design representation sheet generator helps you turn product views into an IPO-style Word document for Indian design applications. Upload perspective, front, back, and side views, edit novelty and disclaimer text, then download the sheet.

IPR Manager is a software platform only. AI tools speed up drafting, but every section, claim, and form stays a draft until you review and confirm it. We do not provide legal advice, patentability opinions, filing services, government-fee collection, or representation before the Indian Patent Office. Verify official fees and dates on ipindia.gov.in before filing.
