What Inventr does

Inventr is the pocket workbench for the solo inventor and the first-time entrepreneur navigating the US patent system without a $400/hour attorney on retainer. It is the binder you wish you had kept five years ago and the prep document you need before your first call with a patent agent.

The US issues ~330,000 patents per year. Hundreds of thousands of provisional applications expire because the inventor forgot the 12-month deadline. Almost every inventor I've talked to has at least one disclosure they 'meant to write down' that they cannot now date-stamp. The first-to-file rule (AIA 2013) makes that fatal.

Inventr is the calm, free, on-device place to keep that record from now on.

What ships in v1:

— Disclosure log: every invention, every novel idea, every public-disclosure event — date-stamped (cryptographic SHA-256 hash of content + timestamp stored locally), tagged by category, with a free-text description and an optional sketch. — Provisional / non-provisional tracker: filing date, application number, examiner, classification (USPC + CPC), claim status, fee schedule, and an automatic 12-month conversion countdown for every provisional in flight. — Prior art notes: for each invention, log USPTO publications, scientific papers, products, and conferences you discovered. With excerpt + your distinguishing rationale. — Claim sketch pad: a free-form text editor for drafting independent and dependent claims, with example syntax templates for apparatus, method, and CRM claims. — USPTO fee catalog: bundled small-entity / micro-entity / large-entity fees for 30+ common transactions — filing, search, exam, RCE, issue, maintenance (3.5/7.5/11.5 yrs), petition fees. Updated to April 2025 schedule. — Deadline tracker: provisional expiry, response to non-final OA (3 months default), response to final OA, IDS-by date, maintenance fee windows, foreign filing under the Paris Convention. — Public-disclosure clock: the US one-year grace period (35 USC 102(b)(1)) — for each disclosure, Inventr tells you the day the foreign filing rights expire and the day the US grace period ends. — No 'Pro,' no in-app purchases. Yours.

Inventr is for the garage inventor on weekend #1, the SaaS founder who just realized their workflow might be patentable, the maker preparing for Maker Faire, and the engineer who keeps inventing things at the day job after-hours.

Inventr is record-keeping software. It is not legal counsel and it is not the USPTO. The date-stamps it produces are local and corroborative; they are not a substitute for a patent attorney.

Why we built it

First-to-file (AIA 2013) makes records mandatory. Provisional applications expire silently at 12 months. USPTO fee schedules are buried. There is no calm consumer iOS app for the solo inventor who wants a date-stamped disclosure log, a deadline tracker, and an offline reference for the fee schedule. Existing tools are…

What makes it different

Inventr is the only iOS app that combines (a) date-stamped on-device disclosure log with SHA-256 content hashes, (b) provisional / non-provisional tracker with automatic 12-month and 3-month countdowns, (c) prior art register, (d) claim sketch pad with apparatus/method/CRM templates, (e) bundled USPTO fee catalog (sma…
