# Your Lead Engineer Legally Owns Your Core Patent. You Forgot the IP Assignment Clause.

A CTO walked out of his Series A startup in Q3 last year. Three weeks later, his former company received a cease and desist letter. He was the sole named inventor on the company's core patent, and he had never signed an IP assignment agreement. The startup did not legally own the single most valuable asset on its balance sheet.

\n\nThis is not a one-off horror story. Beyond Elevation has audited 180+ tech and AI startup IP portfolios in the last 24 months. In 31% of them, at least one critical patent was filed without a properly executed inventor-to-company assignment. Nearly a third of founders are sitting on patents their own engineers legally own.

\n\nYour IP is not yours until the paperwork says it is. And in US patent law, the default rule is brutal: the individual inventor owns the invention, not the company that paid for it.

\n\n## Who Actually Owns the Patents Your Engineers File?

\n\nUnder US patent law, the named inventor is the default owner. Not the CEO. Not the company. Not the investor who funded the R&D. The individual human whose name appears on the patent application holds all rights, unless a signed, written assignment transfers those rights to the company.

\n\nEmployment alone does not transfer patent rights. "We pay him a salary" is not an assignment. "It is in the employee handbook" is not an assignment. "His offer letter mentions IP" is usually not an assignment either. The Federal Circuit has been brutally consistent on this: patent assignment requires specific written language of present conveyance. The magic words are "hereby assigns," not "will assign."

\n\nIn the landmark *Stanford v. Roche* case, Stanford University lost ownership of its own HIV testing patents because the inventor had signed a "will assign" clause with Stanford and a "hereby assign" clause with a third-party collaborator. The third party won. The present-tense language beat the future-tense one. A billion-dollar research programme lost control of its own invention over two verb tenses.

\n\n## Where Are the Assignment Gaps Most Startups Miss?

\n\nThree failure points come up over and over in Beyond Elevation's chain-of-title audits. All of them are fixable. All of them are usually ignored until a dispute, an acquisition, or a funding round exposes the gap.

\n\n### 1. Pre-Incorporation Work by Founders

\n\nThe most common gap. Co-founders build a prototype before forming a company. They write the first version of the code, file a provisional patent in their own name, then incorporate weeks later. The company never formally acquires the pre-incorporation IP because everyone assumes "we founded it, so we own it." You do not own it. The individual founders own it, and when one walks, that IP walks with them.

\n\nThe fix takes ten minutes. Every co-founder signs a contribution and assignment agreement at incorporation, listing and transferring all pre-existing work product related to the business. Skip it and you can lose the company over a resignation.

\n\n### 2. Contractors and Fractional Engineers

\n\nStartups hire fractional CTOs, contract ML engineers, and outsourced development shops constantly. Most contractor agreements include a generic "work product" clause, but those clauses do not cover patent rights. A standard work-for-hire clause conveys copyright in code. It does not automatically convey patent ownership. Those are two different legal animals.

\n\nOne company Beyond Elevation audited had filed seven patents based on work done by a contract engineer who had signed only a boilerplate NDA with a generic copyright clause. The patents were legally owned by the contractor. The company paid six figures to buy back its own IP during acquisition due diligence.

\n\n### 3. Employees Hired Before IP Templates Were Standard

\n\nEvery early-stage company hits a point where they hire ten engineers before anyone drafts a proper IP assignment template. By the time legal formalises the paperwork, those early employees have already built the core product. When HR comes back and asks them to sign the new template, some will sign without friction. Some will use the moment as leverage for equity, cash, or exit packages. The leverage at that moment belongs entirely to the employee.

\n\n## How Do You Close the IP Assignment Gap Before It Costs You Millions?

\n\nThe fix is methodical and fast. Beyond Elevation runs a 30-day IP chain-of-title audit that maps every patent, every inventor, every employment relationship, and every gap in ownership. The deliverable is a ranked list of exposure: which patents are safe, which are at risk, and which need immediate remediation.

\n\n**Run a chain-of-title audit.** For every patent in the portfolio, trace the assignment chain from named inventor to company. If any link is missing or uses "will assign" instead of "hereby assigns," flag it as high risk. USPTO assignment records are public. This audit is a weekend of focused work.

\n\n**Draft a present-tense assignment template.** All future hires and contractors sign this on day one, before they touch a line of code or a whiteboard. Use the explicit words "hereby assigns" in the present tense. Include a schedule listing any pre-existing IP that is carved out. Have it reviewed by actual IP counsel, not general corporate counsel.

\n\n**Remediate historical gaps quickly.** Current employees and former engineers still on good terms will typically sign retroactive assignments for a nominal payment, $500 to $5,000 each. Delay this and the price rises every year. At acquisition due diligence, the price can rise into six figures per holdout, or kill the deal outright.

\n\n**Structure invention disclosure forms.** Every new invention gets documented on a disclosure form signed by every contributor at the moment of conception. This creates a paper trail that makes future assignments trivially enforceable and protects inventorship claims against disputes years later.

\n\n## What Does a Broken Chain of Title Actually Cost You?

\n\nThree buckets. The numbers are not small.

\n\n**Killed or delayed acquisitions.** Beyond Elevation has seen one acquisition die outright and three more delayed by six months or more because of assignment gaps surfaced during IP due diligence. On a $40M acquisition, a six-month delay often means a lower price, a renegotiated earn-out, or a collapsed deal. Position Imaging's 66-patent restructure, led by Beyond Elevation, specifically addressed chain-of-title integrity before any buyer conversation, and that preparation changed the entire downstream valuation negotiation.

\n\n**Licensing revenue you cannot collect.** Companies with patents are 10.2x more likely to secure early-stage funding, and they also have access to licensing as a non-dilutive revenue stream. If your chain of title is broken, you cannot license what you do not legally own. DGS's data monetisation programme with Beyond Elevation was only possible because ownership rights were clean from day one. Clean title is the precondition for every form of IP monetisation.

\n\n**Extortion by departing employees.** The most painful cost. A departing engineer who realises they personally own a granted patent has leverage over the entire company. Settlement payments in the $100K to $2M range are common in these situations and almost never reported publicly. Every one of them was avoidable with a ten-minute signed document at the time of hiring.

\n\n## Frequently Asked Questions

\n\n### What is the legal difference between "will assign" and "hereby assigns"?

\n\n"Will assign" is a promise to assign in the future. It creates a contractual obligation but does not transfer ownership at signing. "Hereby assigns" is a present-tense conveyance that transfers ownership immediately upon execution of the agreement. US courts, especially the Federal Circuit after *Stanford v. Roche*, require present-tense language for effective automatic patent assignment. Beyond Elevation always reviews assignment language for this specific distinction in every chain-of-title audit.

\n\n### Can I retroactively get my employees and contractors to sign IP assignments?

\n\nYes, in most cases. Current employees will usually sign retroactive assignments as a condition of continued employment or in exchange for nominal consideration. Former employees on good terms will typically sign for a modest payment if approached professionally before they realise their leverage. The longer you wait, the more expensive and legally risky this becomes. Beyond Elevation handles these remediation conversations as part of its IP portfolio clean-up engagements.

\n\n### Do standard contractor NDAs cover patent ownership?

\n\nAlmost never. Standard NDAs cover confidentiality obligations, not ownership transfer. Generic work-for-hire clauses cover copyright in deliverables but do not automatically convey patent rights. Contractors must sign a specific IP assignment agreement containing present-tense "hereby assigns" language to transfer patent ownership to your company. If your current contractor paperwork does not include this, every patentable invention they touch is at risk.

\n\n### How do I audit my existing IP portfolio for assignment gaps?

\n\nStart with the USPTO assignment database, which is public. Cross-reference every named inventor on every patent against your employment and contractor records. Flag every patent where the assignment was recorded late, missing, or references only a generic employment agreement. Beyond Elevation runs a systematic chain-of-title audit that typically takes two to four weeks and identifies every exposure in the portfolio before it becomes a fundraising, licensing, or acquisition problem.

\n\nYour patents are only as valuable as your ability to prove you own them. In 31% of startup portfolios Beyond Elevation reviews, that proof is broken. Fix the chain of title before a buyer, an investor, or a departing engineer finds the gap first. Beyond Elevation builds the IP ownership architecture that holds up under due diligence, every time.
