ITC Section 337 patent litigation is the enforcement route most patent holders never consider, and for a specific set of facts it is the strongest one available.
It is fast. An initial determination typically arrives around twelve to sixteen months from institution, against two to four years in district court.
The remedy is exclusion, not money. An exclusion order stops infringing goods at the border. The Commission cannot award damages at all.
And there is a threshold most complainants have to clear. A domestic industry relating to the patent must exist, which is what decides who can use the forum.
A note on the abbreviation
ITC collides with two unrelated things, and the collision causes real confusion in search and in documents.
| ITC means | Field |
|---|---|
| International Trade Commission | Patent and trade |
| Investment Tax Credit | Tax and energy finance |
| IRC section 337 | Corporate tax — liquidations |
Always write "ITC Section 337" in a patent context, and spell out International Trade Commission on first use. "Section 337" alone is ambiguous with the tax provision.
How it differs from district court
| ITC Section 337 | District court | |
|---|---|---|
| Remedy | Exclusion and cease-and-desist orders | Damages, injunction |
| Damages available | No | Yes |
| Speed | ~12–16 months to initial determination | 2–4 years |
| Decided by | Administrative law judge, then the Commission | Judge or jury |
| Jurisdiction | Imported goods | Any infringing act |
| Threshold | Domestic industry required | None |
| Injunction test | No eBay four-factor test | eBay applies |
| Presidential review | Yes, 60 days | No |
| Appeal | Federal Circuit | Federal Circuit |
| Preclusive on validity | No | Yes |
The absence of the eBay test is significant. In district court a patent holder must satisfy the four equitable factors to obtain an injunction, and holders who do not practise the invention frequently fail. At the ITC, exclusion follows a violation finding subject to public interest factors.
No damages is the corresponding cost. A complainant wanting money must run a parallel district court action.
The domestic industry requirement
Two prongs, both required.
| Prong | Requires |
|---|---|
| Technical prong | An article protected by the patent exists |
| Economic prong | Significant or substantial US investment relating to it |
| Economic prong routes | Standard |
|---|---|
| Plant and equipment | Significant investment |
| Labour or capital | Significant employment |
| Engineering, R&D or licensing | Substantial investment |
An operating company with US manufacturing clears it easily. The investment is visible and documented.
A licensing entity has a harder path. The licensing prong exists, and the standard for substantial investment in licensing has been applied strictly, so a portfolio holder with no US operations cannot assume access.
The technical prong needs an article practising the patent, which is why a patent covering something nobody makes is difficult to assert here regardless of investment.
The procedure
| Stage | Timing |
|---|---|
| Complaint filed | Day 0 |
| Institution decision | ~30 days |
| Target date set | Early |
| Discovery | Compressed and intense |
| Evidentiary hearing before the ALJ | ~9–11 months |
| Initial determination | ~12–16 months |
| Commission review | ~2–4 months |
| Final determination and remedy | — |
| Presidential review | 60 days |
| Federal Circuit appeal | Optional |
Institution is near-automatic. Unlike a PTAB petition, the Commission institutes almost all properly pleaded complaints, so the filtering happens later.
Discovery is the shock for respondents. The compressed schedule means document production, depositions and expert work all happen in months rather than years, and the burden falls hardest on the party holding the documents.
The target date drives everything, and extensions are rare.
Remedies
| Order | Effect |
|---|---|
| Limited exclusion order | Bars importation by named respondents |
| General exclusion order | Bars importation regardless of source |
| Cease-and-desist order | Bars sale of already-imported inventory |
| Bond during Presidential review | Allows importation on bond for 60 days |
A general exclusion order is the strongest remedy in US patent law. It excludes infringing goods from any source, including parties never named, and it is granted where circumvention is likely or sources are hard to identify.
Cease-and-desist orders close the domestic gap. An exclusion order stops goods at the border; existing US inventory needs the second order.
Customs enforces exclusion orders, which shifts the burden of policing from the patent holder to a government agency.
Parallel district court actions
| Feature | Detail |
|---|---|
| Both can run | Yes |
| Respondent's stay right | 28 U.S.C. 1659 — mandatory on request |
| What the ITC decides | Exclusion |
| What the district court decides | Damages |
| ITC findings preclusive? | No |
| Record usable in court | Influential in practice |
The stay is a statutory right for a respondent, not a discretionary decision, so the district court case pauses while the ITC proceeds.
Which means the sequence is set. ITC first for exclusion, district court afterwards for damages, with the ITC record informing the second case without binding it.
When the ITC fits
| Factor | Favours the ITC |
|---|---|
| Infringing goods are imported | Essential |
| Complainant has US operations | Essential in practice |
| Speed matters | Strongly |
| Exclusion is worth more than damages | Strongly |
| Respondents are foreign and hard to reach | Strongly |
| Multiple infringing sources | General exclusion order |
| Complainant wants money | Against |
| No domestic industry | Disqualifying |
The classic fit is a US manufacturer facing imported competition. Speed, exclusion and Customs enforcement all align with what they need.
The classic misfit is a patent holder seeking a settlement payment. No damages are available, and the domestic industry requirement may not be met.
Public interest factors
The Commission must consider four before granting a remedy.
| Factor |
|---|
| Public health and welfare |
| Competitive conditions in the US economy |
| US production of like or directly competitive articles |
| US consumers |
These rarely defeat a remedy, but they have occasionally shaped one — for example where excluding a product would create a supply shortage with no adequate domestic alternative.
Respondents raise them routinely and complainants should expect to address domestic supply capacity.
Worked example: choosing the forum
A US manufacturer facing imported competition from three foreign suppliers.
| ITC Section 337 | District court | |
|---|---|---|
| Time to remedy | ~15 months | 3 years |
| Remedy available | Exclusion order | Damages, injunction uncertain |
| Reaching foreign respondents | Straightforward — goods at the border | Difficult — service and enforcement |
| Damages | None | Available |
| Domestic industry | Met — US plant and R&D | N/A |
| Cost | High, compressed | High, extended |
| Enforcement | US Customs | Contempt proceedings |
The decision
ITC, with a parallel district court case stayed.
| Reason | Weight |
|---|---|
| Foreign respondents hard to reach in court | Decisive |
| Exclusion stops the commercial harm | Decisive |
| Speed preserves market position | High |
| Damages pursued later in the stayed case | Preserved |
| General exclusion order sought | Three sources, more suspected |
Reaching foreign respondents was the deciding factor. A district court judgment against a foreign manufacturer with no US assets is difficult to enforce; an exclusion order enforced by Customs is not.
The damages claim was not abandoned, only deferred to the stayed district court action.
Costs and burden
| Feature | Effect |
|---|---|
| Compressed schedule | High spend over a short period |
| Discovery intensity | Heavy on the respondent |
| Multiple respondents | Complainant's cost spread; respondents' individual |
| Expert work | Substantial |
| No damages phase | Removes one expensive component |
The total is comparable to district court litigation and arrives faster, which suits a complainant with a market position to defend and pressures a respondent without deep reserves.
Respondents face the same asymmetry as in ordinary patent litigation, with less time to absorb it. See patent litigation.
ITC Section 337: the checklist
- Write "ITC Section 337" explicitly. The abbreviation collides with Investment Tax Credit and IRC 337.
- Confirm the goods are imported. The forum has no jurisdiction otherwise.
- Establish the domestic industry early — both technical and economic prongs.
- Assess the licensing prong realistically if you have no US manufacturing. It is applied strictly.
- Decide whether exclusion or damages matters more. The ITC gives only the first.
- Consider a parallel district court action for damages, expecting it to be stayed.
- Plan for compressed discovery. The target date does not move.
- Seek a general exclusion order where sources are numerous or circumvention is likely.
- Address the public interest factors, including domestic supply capacity.
- Remember ITC findings are not preclusive on validity in district court, so the second case starts fresh on that question.
