ITC 337 Modification Proceedings: Scope Changes and Design-Around Adjudication

TL;DR
Any party can request modification of an ITC exclusion order to narrow its scope, clarify its application to a design-around, or address changed circumstances (for example, patent expiration, invalidity, or a successful design-around). Modification proceedings are conducted by the ITC and typically take 6-12 months. A favorable modification can allow redesigned products to be imported without risk of seizure or contempt. See our ITC 337 exclusion order enforcement guide by the PatentPaper research team for customs practice and our ITC 337 advisory opinions guide by the PatentPaper research team for pre-import clearance.

Who Can Request Modification and on What Grounds

Any interested party (respondent, complainant, importer, or third party) can request modification. Common grounds include: the patent has expired or been invalidated; the respondent has implemented a design-around that should be excluded from the order; the order is broader than necessary to remedy the violation; or changed circumstances (for example, new suppliers, new products, or changes in the market) make the order no longer appropriate. The ITC has discretion to grant or deny the request.

Example: In a 2023 modification proceeding, a respondent subject to a limited exclusion order on semiconductor packaging equipment requested modification to exclude a redesigned process that used a different bonding technique and a different interposer. After briefing, evidence, and a hearing, the ITC modified the order to exclude the redesigned process, finding that it was a genuine design-around that did not infringe the asserted patents.

Procedure, Timing and the Role of OUII

Modification proceedings are conducted by the ITC's Office of Unfair Import Investigations (OUII) with an opportunity for the parties to submit briefing and evidence. The process typically takes 6-12 months from institution to Commission decision. OUII often plays an active role in developing the record and may take a position on whether the order should be modified.

Evidentiary Requirements and the Burden of Proof

The requesting party bears the burden of showing that modification is warranted. For design-around requests, the respondent must provide sufficient evidence for the ITC to compare the redesigned product with the excluded product and the patent claims. The ITC applies a "colorable difference" analysis similar to contempt proceedings. Minor changes that do not alter the way the product appears or functions relative to the excluded design are usually found to be within the scope of the order.

Strategic Use by Respondents and Third Parties

Modification proceedings are most valuable when a respondent has developed a design-around and wants to import the redesigned product with reduced risk of seizure or contempt. Third parties (distributors, contract manufacturers, or downstream product makers) can also use modification proceedings to clarify whether their products fall within the scope of an order that names other parties.

Limitations and the Possibility of Reconsideration or Appeal

A modification order can be reconsidered if circumstances change or new evidence emerges. The Commission's decision on modification is subject to appeal to the Federal Circuit. A favorable modification is highly persuasive but does not guarantee that Customs will release the product or that a contempt proceeding will not be initiated if the complainant disagrees with the ITC's analysis.

FAQ

How long does an ITC modification proceeding take?

Typically 6-12 months from the date the request is instituted. The exact timeline depends on the complexity of the issues, the volume of briefing, and whether a hearing is held.

Can I request modification before I have a final design-around?

Yes, but the request must describe the proposed product with sufficient specificity for the ITC to make a meaningful determination. Vague or hypothetical descriptions are likely to be rejected or result in an inconclusive decision.

Is a modification order binding on Customs?

No. Modification orders are not binding on Customs, although Customs will often give them significant weight. A favorable modification reduces but does not eliminate the risk of detention.

Can the complainant challenge a favorable modification order?

The complainant can petition the ITC for reconsideration or modification of the order if new evidence or changed circumstances arise. The complainant can also initiate a contempt proceeding if it believes the imported product violates the order despite the modification.

Can third parties request modification of an exclusion order?

Yes. Any interested party can request modification, including distributors, contract manufacturers, or downstream product makers who are not named in the original investigation.

Does requesting modification waive any rights or create estoppel?

Generally no. Requesting modification does not waive the right to argue in other proceedings that the product does not infringe or that the order is invalid or overbroad. However, positions taken in the modification proceeding may be used as admissions or for impeachment in later proceedings.

Which PatentPaper resources cover ITC remedy scope and enforcement?

Our ITC 337 exclusion order enforcement and ITC 337 advisory opinions articles by the PatentPaper research team analyze modification proceedings, remedy scope, and enforcement at the border.

Review layer 1: Practical review notes for ITC 337 Modification Proceedings: Scope Changes and Design-Around Adjudication

Review layer 1: For itc 337 modification proceedings, separate the legal basis, patent-office step, and commercial evidence needed in a dispute. Sources such as usitc.gov, cafc.uscourts.gov, cbp.gov help confirm fees, deadlines, term, and forum from primary material rather than secondary summaries.

Review layer 1: Before filing, licensing, assigning, challenging, or enforcing the right, keep a matrix with the application number, owner, prosecution status, payments, agreements, and related PatentPaper links. That record makes later decisions easier to defend.

Review layer 1: Check legal status before sending a notice.
Review layer 1: Save official receipts and office correspondence.
Review layer 1: Compare the main claim with the product actually sold.
