Soon-to-Expire: Timing the Opportunity

Every important market window has a clock. When patents lapse, the walls around proven technology fall. If you’re set up before that moment, you can launch fast, undercut costs, and frame the story while bigger players hesitate. This guide shows you how to time that window and be first when inventions enter the public domain.

What “soon-to-expire” really means

Before you move, get the basics right:

Utility patents (US): usually expire 20 years from the earliest non-provisional filing (watch for continuations that change the date).
Design patents (US): 15 years from grant.
Early lapses: a patent can die before the term if maintenance fees aren’t paid.
Extensions & adjustments: pharma/biotech and some agro can have PTE/SPC or PTA that push the date.
Family risk: even if one patent expires, family members (continuations/divisionals in other countries) might still block you.
Regulatory exclusivity: drugs, med devices, and chemicals may face non-patent barriers even after patents end.

Rule of thumb: treat the “headline date” as a signal, not permission. Always confirm freedom to operate.

Why timing beats size

No royalty drag: your COGS drops the day protection ends.
Speed advantage: incumbents wait for legal sign-off; startups can ship.
Narrative control: launch first and set the category language around a now-public technology.
Investor signal: “pre-expiry readiness” looks like a plan, not a gamble.

Your Timing Stack (6 building blocks)

Scope the target space
- Map CPC/IPC classes and key assignees.
- Pull a list of patents with ≤ 36 months to expiry or likely fee lapse.
Do the expiration math
- Compute term, add/subtract PTA/PTE/SPC, and mark maintenance-fee cliffs.
- Track by family, not a single asset.
Flag blockers early
- Active claims in siblings, method vs device coverage, and country differences.
- Non-patent barriers: standards compliance, data exclusivity, trademarks.
Validate demand timing
- Pair each soon-to-expire item with a customer job and a trend trigger (regulatory change, cost swing, standard adoption).
Line up supply
- Lock component substitutes, manufacturers, or APIs.
- Pre-build a minimal prototype that avoids still-active claims.
Launch playbook
- Draft positioning: “proven tech, better price, shipped now.”
- Prep content and channels so your campaign starts the week protection ends.

A simple timeline you can run (T = expiration day)

T-180 to T-120 (Discovery & design)
- Long-list targets; calculate terms; shortlist 3–5 families.
- Customer calls: confirm use-cases and must-have features.
- Sketch a design that sidesteps any still-active claims.
T-90 (Legal and sourcing)
- Commission a focused FTO review on your final concept.
- Lock suppliers; price the BOM; plan version A (day-0) and B (post-feedback).
T-60 (Prototype & pilots)
- Build pilot units or a working software module.
- Run 2–3 paid pilots; capture testimonials and failure modes.
T-30 (Go-to-market)
- Finalize packaging, pricing, warranty/SLAs.
- Queue launch pages, email sequences, ads, and a press brief.
T-0 (Launch)
- Flip distribution; publish case studies; announce price/value compared to licensed alternatives of yesterday.
T+30 (Tight loops)
- Ship fixes; trim costs; double down on the best channel.

Checklists you can paste into your doc

Expiration math (pass/fail)

Earliest non-provisional date confirmed
PTA/PTE/SPC checked
Maintenance-fee status checked
Family tree reviewed (US + key markets)
No terminal disclaimer that shifts the date
Claims read vs your final design

Freedom-to-operate sanity

Independent claims mapped to your features
Active siblings/regionals assessed
Standards-essential risk considered
Trademarks/brand cleared
Regulatory exclusivity noted (if any)

Commercial readiness

Unit economics ≥ target gross margin
Supplier MOQs and lead times secured
Support, returns, and compliance ready
Channel and messaging tested with real buyers

Mini-patterns (use them as templates)

Generic pharma
- Track compound + formulation + use claims.
- Lock manufacturing and QA well before T-0.
- Launch with payer-friendly pricing and inventory certainty.
Industrial hardware
- Many patents expire quietly; the process might still be covered while the fixture is free to copy.
- Pre-sell to maintenance and retrofit teams; offer install kits at T-0.
Software/algorithms
- Code isn’t patented; methods may be. When method patents lapse, you can ship features others avoided.
- Pair with content showing measurable time or cost savings.

Common pitfalls (avoid these)

Chasing the date, ignoring the family. One asset expires while a sibling blocks your SKU.
Copy-paste cloning. Claims can cover variants; adapt the design.
Underestimating supply. You can be first and still stock out.
Skipping regulatory checks. Especially in health/chem/energy.
Forgetting brand. Names, packaging, and domain availability matter on day one.

The investor story (metrics they want)

Time to market: days from T-0 to first revenue.
Unit margin: margin delta vs licensed alternatives.
Pipeline: number of soon-to-expire bets in the next 12–24 months.
Moats: cost position, channel control, and speed of iteration.

Put it to work with UnlockedPatents

Use a simple flow:

Create a “Soon-to-Expire” watchlist for your CPC classes and target assignees.
Get alerts at T-180, T-90, T-30, and T-0 for each family.
Open the family view to see siblings and country coverage.
Export a one-page FTO prep sheet for counsel.
Attach a go-to-market checklist and assign owners/dates.

Bottom line: timing isn’t luck. It’s a system. Build your stack, run the timeline, and be ready when proven tech becomes fair game.
