Pratyasa

A patent, on the record.

A fast, self-contained page for granted patent IN 429867 — a point-of-care sepsis-biomarker biosensor — so there is finally somewhere to point when someone asks what Tushar built.

The problem

The invention was real. Its record didn’t exist.

The patent is granted, the prototype exists and the science is published — but there was no page, no narrative, nowhere to point a recruiter or collaborator who asks “what did you actually build?”

The page

One fast page that tells the truth about the work.

Tushar worked across the analyser’s electronics and firmware, the Android app, sensor preparation and validation testing in blood and food samples. The page shows that work with the certificate, the paper and device footage.

Decisions

Contributor, not owner. Prototype, not diagnostic.

  • Could have
    A sales page for patent buyers
    Chose
    A general credibility page
    Because
    The second revision reframed the audience: recruiters, collaborators and colleagues, not buyers.
  • Could have
    Present the patent as Tushar’s
    Chose
    Contributor framing, true to the paper
    Because
    It must stay true when a reader clicks through: the patent is owned by NIT–Calicut.
  • Could have
    Let it read like a medical product
    Chose
    “Research prototype, not an approved diagnostic”
    Because
    A biosensor page must never imply regulatory approval.

How it stays true

Every fact is locked, then checked.

Evidence

Live, and linked from the scroll-film portfolio.

The device itself was validated in whole blood, mayonnaise and fruit juice, as reported in the published paper. Those are science results, not product metrics.

What isn’t measured

  • No traffic or visit data is recorded for the page.
  • The Soft Matter paper’s DOI is still missing from the record.

Sources

Everything here is backed by a real artifact.
