Background
InterDigital Communications held patents essential to the 3G wireless telecommunications standard — covering technologies that all compliant mobile devices must implement. InterDigital’s business model was entirely built around licensing: it did not manufacture mobile devices or network equipment, but invested heavily in research, standards participation, and licensing its patent portfolio to virtually every major handset manufacturer in the world.
When Nokia disputed InterDigital’s licensing terms, InterDigital brought a Section 337 complaint at the International Trade Commission (ITC), seeking an exclusion order — a remedy that would ban importation of Nokia’s devices into the U.S. To obtain relief under Section 337, a complainant must establish a “domestic industry” relating to the articles protected by the patents. Section 337(a)(3)(C) expressly includes “substantial investment in its exploitation, including engineering, research and development, or licensing” as a qualifying domestic industry. The ITC’s initial ruling found that InterDigital’s licensing activity did not constitute a qualifying domestic industry.
The Court’s Holding
The Federal Circuit affirmed the panel decision that InterDigital’s patent licensing activities alone satisfied the domestic industry requirement under Section 337(a)(3)(C). InterDigital had invested over $7 million in employee compensation for its licensing staff and received nearly $1 billion in licensing revenue from agreements that included the patents-in-suit. The court held this was a “substantial investment” in the exploitation of the patents through licensing — precisely what Congress intended when it added the licensing prong to the domestic industry statute.
The court also addressed a key structural requirement: to satisfy the licensing prong, the domestic investment must be tied to articles that are actually protected by the asserted patents — licensees must make products that practice the patents. Because InterDigital’s licensees manufactured 3G-compliant devices that practiced its standard-essential patents, this requirement was met. Pure financial licensing of a patent with no practicing articles connected to it would not suffice.
The denial of en banc rehearing came with separate opinions debating the broader policy implications — whether allowing NPEs to use ITC exclusion orders created leverage that undermined the balance between patent holders and implementers in the standards context.
Key Takeaways
- A pure licensing business with no domestic manufacturing can establish the ITC’s domestic industry requirement through substantial investment in licensing activities under Section 337(a)(3)(C).
- The licensing investment must be tied to articles that are actually protected by and practice the asserted patents — purely passive financial licensing with no practicing articles is insufficient.
- The decision significantly empowered non-practicing entities (NPEs) and patent licensing companies to use the ITC as a patent enforcement forum, with access to the powerful remedy of import exclusion orders.
- The case intensified debate about whether NPEs should have access to ITC exclusion orders — a remedy whose primary purpose (protecting domestic industries from unfair foreign competition) arguably does not fit pure licensing businesses that make nothing in the U.S.
Why It Matters
InterDigital v. ITC is one of the most consequential ITC decisions of the last two decades for the patent licensing industry. By confirming that licensing-only businesses qualify as domestic industries, the Federal Circuit opened the ITC as a forum for patent licensing companies — including both legitimate technology developers like InterDigital and more aggressive NPE litigation funds. The ITC’s exclusion order remedy is often more powerful than district court damages because it operates at the border and can bar an entire product line from import regardless of other legal proceedings.
For standards-essential patents specifically, the decision raised concerns about hold-up: an NPE holding SEPs could seek an ITC exclusion order against a standard-compliant implementer, creating enormous leverage for licensing negotiations — even if the FRAND commitment required reasonable licensing terms. Subsequent ITC investigations and Federal Circuit decisions have continued to wrestle with the intersection of FRAND commitments and the ITC’s exclusion-order authority.
