Can we mine old or abandoned projects for patentable inventions?

Projects rarely die because the engineering failed. They die because the market was early, the funding moved, or the company pivoted, and the inventions made along the way die with the slide decks. Years later the market often arrives where the old work pointed, and competitors begin filing in exactly the space your shelved project explored. That is the moment mining pays.

The hunting ground is wider than cancelled products. Unfiled disclosures sitting in old review queues, lapsed provisional applications, abandoned patent applications, internal tools that were never productized, and conference papers or theses by your own staff all hold candidate inventions. So do the rejected alternatives inside successful projects: the approach your team considered and set aside may still be the approach a competitor will try.

Start with an inventory pass over the artifacts: repositories, design documents, lab notebooks, old disclosure databases, and patent committee minutes. Triage the candidates against the current roadmap and competitive landscape, because an invention is only worth recovering if it protects where you or your competitors are going. Then interview the reachable inventors in facilitated sessions, run like harvesting but archaeological: the facilitator reconstructs mechanism and alternatives from memory and fragments, and drafts the disclosures. The inventors only have to talk, which matters when they have moved roles and have no time for paperwork.

Before money is spent on drafting, two screens apply, and both belong to your patent counsel: whether any public disclosure has already closed the filing window, and whether the invention is still novel against the art that has accumulated since. A quick novelty search before drafting is cheap insurance on older material. ipCG runs the inventory, facilitation, and disclosure work; the legal judgments stay with counsel.

Expect attrition from four directions. Disclosure bars: work that shipped, published, was presented, or was open-sourced may already be unfilable, especially outside the US; whether a clock ran is a legal determination. Staleness: an idea from 2018 may now be anticipated or rendered obvious by intervening art, which is why the novelty screen comes before drafting. Enablement gaps: if nobody remembers how the prototype actually worked and the only record is a marketing deck, there may not be enough substance to disclose. And ownership: where contractors or departed employees were involved, assignment agreements usually capture the rights, but counsel should verify before you invest.

Even with attrition, the economics are attractive because the inventing is already done. You are paying for recovery and documentation, with business-grade disclosures typically running about $7,000 each and closer to $5,000 in volume, rather than funding new R&D.
