Patent workflow: how an invention moves through an organisation

By Ipiry TeamPublished August 30, 20269 min read

Short answer

A patent workflow runs in five stages: capture disclosures, triage them, decide whether to file, prosecute what is filed, and then loop through renewal decisions for twenty years. Most failures happen at handoffs rather than within stages — a disclosure nobody triages, a continuation window nobody owns, a fee reminder routed to a distribution list. Naming an owner for each transition matters more than optimising any single stage.

A patent workflow is five stages and about twenty years, and most of what goes wrong happens between stages rather than inside them.

Capture, triage, decide, prosecute, renew.

Each stage is usually handled competently. The disclosure gets written, counsel drafts well, the examiner is answered.

What fails is the handoff — a disclosure nobody picks up, a continuation window nobody owns, a fee reminder that reaches a distribution list.

Why handoffs fail

Reason	Detail
No named owner	The root cause
Ambiguous trigger	Nobody knows when to act
No escalation	Silence goes unnoticed
Reminder to a group	Diffused responsibility

The short version

Name an owner for every handoff. That single practice prevents most losses.

The five stages

Stage	Owner	Typical duration
1. Capture	Inventors	Ongoing
2. Triage	Commercial + counsel	Weeks, ideally
3. Filing decision	Whoever holds budget	Days
4. Prosecution	Counsel	2–4 years
5. Renewal loop	Portfolio owner	Up to 20 years

Stage five is the longest and the least owned. It recurs three times per US patent and annually per foreign member.

Handoff owners at a glance

Transition	Owner
Inventor → triage	Named triager
Triage → filing	Budget holder
Allowance → continuation	Named, diarised
Grant → docket	Automatic
Docket → decision	Named portfolio owner

Stage 1: capture

Trigger	Quality
A non-obvious solution to a real problem	Correct
Before any external disclosure	Critical
Project milestone	Catches inventions late
Annual review	Far too late
Someone remembers	Unreliable

Milestone-triggered capture catches inventions after trade shows and customer demonstrations, by which point foreign rights may already be forfeited.

Train engineers on what triggers a disclosure and on what constitutes public disclosure — trade shows, conference papers, crowdfunding pages and offers for sale all count. See invention disclosure.

Speed matters more than sophistication

Measure	Target
Disclosure to first response	Days
Disclosure to decision	Weeks
Decision communicated	Always
Reasons given for a no	Teaches the next one

Stage 2: triage

Step	Question	Cost
1	Is it commercially relevant?	Free
2	Free prior art search	Free
3	Patentable?	Counsel time
4	Patent, publish, or keep secret?	Strategy
5	Where to file	Markets and manufacturing

Most disclosures should not become applications. A good process says no in weeks.

Slow triage costs foreign rights, because launches happen on their own schedule while a disclosure sits unreviewed.

Step four is a real fork. Filing forecloses trade secret permanently once the application publishes at eighteen months.

Stage 3: the filing decision

Input	Detail
Prior art position	From the search
Commercial relevance	Does anyone practise this?
Budget	$8,000–$20,000 to grant
Provisional or non-provisional	Defers cost 12 months
Jurisdictions	Where you sell and where competitors manufacture
Any disclosure already made	Sets the deadlines

A provisional defers the main spend by twelve months without consuming term, which is why it suits inventions still being tested.

The twelve-month deadline is unextendable and it governs foreign filing too. See how to file a patent.

Stage 4: prosecution

Event	Timing	Owner
Filing receipt	Weeks	Counsel
Publication	18 months from priority	Automatic
First office action	19.9 months average, FY2024	Counsel
Response	3 months, extendable	Counsel + inventors
Continuation decision	At notice of allowance	Frequently unowned
Issue fee	3 months, no extension	Counsel
Disposal	26.3 months average, FY2024	—

The continuation decision is the handoff that fails most. Counsel reports an allowance, which reads as good news, and the window closes when the patent issues.

Give it an explicit owner and a diary entry triggered by the notice of allowance, not by the issue fee. See continuation patent application.

The loop never ends until the patent does

Year after grant	Event
3.5	First decision
7.5	Second decision
11.5	Third decision, largest fee
Annually, abroad	Per country
Term end	Public domain

Stage 5: the renewal loop

Fee	Due after grant	Large	Small	Micro
First	3.5 years	$2,150	$860	$430
Second	7.5 years	$4,040	$1,616	$808
Third	11.5 years	$8,280	$3,312	$1,656
Total		$14,470	$5,788	$2,894

Four options at every window, and two happen by default.

Option	Requires action?	Ends the fee?	Pays you?
Pay	No — the default	No	No
Sell	Yes, months ahead	Yes	Yes
License	Yes	No	Yes, ongoing
Lapse	No — the default	Yes	No

Ipiry Patent Survival Curve v1.0	Rate
Survive the 3.5-year fee (2022 cohort)	85.8%
Survive the 7.5-year fee (2018 cohort)	64.6%
Reach full term (2014 cohort)	41.4%
Abandoned before full term	58.6%

Computed from 27,273,654 USPTO maintenance fee records covering 8,262,336 US utility patents — see the patent survival curve.

Automating the reminder is right; automating the decision is not. Payment by default keeps patents nobody would consciously renew.

Where the handoffs break

Handoff	Failure	Fix
Inventor → triage	Disclosure sits unread	Named triager, SLA
Triage → filing	Decision never made	Explicit yes or no
Filing → prosecution	Inventor unavailable for responses	Named technical contact
Allowance → continuation	Nobody owns it	Diary entry on allowance
Grant → docket	Matter never docketed	Automatic on issue
Docket → decision	Reminder to a distribution list	Named owner
Decision → sale	Started too late to sell	12-month lookahead

Every row is a person, not a system. Software surfaces the deadline; it cannot own the transition.

Reviewing the workflow itself

Ask annually	Detail
Did anything lapse by accident?	The sharpest measure
How long did triage take?	Weeks or months
Were continuation decisions made?	Or missed
Does every handoff have an owner?	The root question

Roles across the workflow

Role	Owns
Inventors	Disclosure quality, alternatives, technical detail
Commercial	Relevance, budget, renewal decisions
Counsel	Drafting, prosecution, legal judgement
Docketing	Deadlines and reminders
One named person per matter	The handoffs

The last row is what most organisations lack, and it is where assets are lost.

Foreign filings add decision points

Point	Timing
Paris Convention filing or PCT	12 months from priority
PCT national phase entry	~30 months from priority
European validation	Short window after grant
Annuities	Annual, per country

A four-country family generates roughly twenty deadlines a year, against three US fee windows across a patent's life. See patent annuity fees by country.

Worked example: two workflows

	Organisation A	Organisation B
Disclosure trigger	Project milestone	On solving a problem
Triage time	4 months	3 weeks
Prior art search	After counsel review	First, free
Continuation owner	None named	Named, diarised
Fee reminders to	Distribution list	Named owner
Annual portfolio review	No	Q1, 18-month lookahead

Outcomes over three years

	Organisation A	Organisation B
Foreign rights lost to prior disclosure	2 inventions	0
Families closed at allowance	4	0
Patents lapsed by accident	1	0
Patents released deliberately	0	6, two sold first
Spend on applications that failed §102	Higher	Lower

Organisation A had no bad stages. Counsel was competent, engineers disclosed, deadlines were calculated.

Every loss came from a handoff nobody owned.

Organisation B released more patents deliberately, which is the process working rather than failing.

Tooling at each stage

Stage	Minimum	At volume
Capture	A form	Disclosure software
Triage	A meeting and a spreadsheet	Workflow tool
Prosecution	Counsel's system	Shared visibility
Renewal	A calendar with both dates	Docketing software or a service
Portfolio review	A spreadsheet	Portfolio tool

The discipline matters more than the tool at every stage. A calendar owned by a named person outperforms software routed to a distribution list.

Measuring whether it works

Measure	Good
Disclosure to triage decision	Weeks, not months
Share of disclosures reaching a decision	Near 100%
Deadlines actioned before the final month	High
Lapses that were decisions, not accidents	All of them
Sales started 12 months before a deadline	Some
Entity status rechecked at each payment	Always

"Lapses that were decisions" is the sharpest single measure. Releasing patents is normal; losing them is not.

What never gets automated

Task	Why
The renewal decision	Commercial judgement
Entity status determination	Depends on your circumstances
Whether to respond or abandon	Legal judgement
Whether to file a continuation	Strategic
Verification against office records	Minutes, catches everything

Entity status is the trap. Growth past 500 employees or a licence to a large company ends small entity eligibility, and paying at the wrong rate can render a patent unenforceable. See small entity status.

Patent workflow: the checklist

Name an owner for every handoff, not just every stage.
Trigger disclosure on solving a problem, not on a project milestone.
Run the free prior art search during triage, before counsel time.
Decide patent, publish or secret before filing forecloses the last two.
Triage in weeks. Slow review costs foreign rights.
Diarise the continuation decision on notice of allowance.
Route fee reminders to a named person, never a distribution list.
Automate reminders, not decisions.
Run an annual review with eighteen months of lookahead, so selling stays possible.
Measure lapses that were decisions. Releasing is fine; losing is not.

Common questions

What is a patent workflow?

The sequence an invention follows inside an organisation — from an inventor's disclosure through triage, the filing decision, prosecution, grant, and then the renewal decisions that recur for the life of the patent.

Where do patent workflows usually break?

At handoffs. A disclosure submitted and never triaged, a continuation window nobody owns, a fee reminder routed to a group address. The stages themselves are generally handled well; the transitions between them are where assets are lost.

Who should own each stage?

One named person per transition, not a team or a distribution list. Capture belongs with engineering, triage with whoever holds the commercial view, prosecution with counsel, and renewal decisions with whoever knows if the patent still matters.

How long does the whole workflow take?

Filing to grant is typically two to four years, with a first office action averaging 19.9 months from filing. After grant the renewal loop runs for up to twenty years from filing, with decisions at 3.5, 7.5 and 11.5 years.

What should trigger a disclosure?

Solving a problem in a non-obvious way, and specifically before any external disclosure or offer for sale. Many organisations tie it to project milestones, which catches inventions late — after trade shows and customer demonstrations.

How should disclosures be triaged?

Commercial relevance first, then a free prior art search, then a patentability assessment by counsel. Most disclosures should not become applications, and a good process reaches that answer in weeks rather than months.

What is the most commonly missed step?

The continuation decision at notice of allowance. Nothing prompts it, the parent granting feels like success, and the window closes permanently in the same moment. It needs an explicit owner and a diary entry.

Should the renewal loop be automated?

The reminders should be; the decision should not. Automatic payment converts a four-way commercial decision into a standing order, which is why 58.6% of US utility patents are eventually abandoned — often later and more expensively than necessary.

How does the workflow differ for foreign filings?

It adds a decision point at twelve months for Paris Convention filings or a PCT, then another at roughly thirty months for national phase entry, then annual annuity decisions per country rather than three US fee windows.

What tooling does a workflow need?

At minimum a disclosure intake, a docket that tracks both the window opening and the grace period closing, and reminders reaching named people. Software helps at volume; the discipline matters more than the tool.

How do I know if the workflow is working?

Measure time from disclosure to triage decision, the share of deadlines actioned before the final month, and whether any lapse in the last two years was a decision rather than an accident. Those three tell you most of it.

What should never be automated?

Entity status determination and the renewal decision. Both depend on circumstances and commercial knowledge that no system holds, and getting entity status wrong can render a patent unenforceable.

Invention disclosure: the form and the process

What an invention disclosure form captures, why the date and witness matter, how organisations triage disclosures, and what belongs in the form before counsel sees it.

The patent application process

Every stage from drafting to grant, with real USPTO timings, what happens at each office action, the deadlines that cannot be missed, and where applications actually stall.
