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.
