Scenario: You are a manufacturer importing components that are similar to a patented product.

Your Rights: You have the right to import products that do not literally infringe a patent and do not infringe under the doctrine of equivalents.

What To Do: Carefully analyze the patent claims and compare them to your imported product. Consult with patent counsel to assess the risk of infringement, particularly regarding claim limitations and potential equivalents.

Scenario: You are a patent holder seeking to block imports of competing products under Section 337.

Your Rights: You have the right to seek exclusion of infringing articles if you can demonstrate a violation of Section 337 and the existence of a U.S. domestic industry.

What To Do: Ensure your patent claims are clearly defined and that your imported products meet all limitations. Be prepared to demonstrate a substantial U.S. economic activity related to the patent.

Is it legal to import products that are similar to a patented item?

Depends. It is legal to import products that do not literally infringe a patent and do not infringe under the doctrine of equivalents. However, if the imported product is substantially the same as the patented invention, it may be illegal.

This applies to U.S. import law, specifically Section 337 of the Tariff Act of 1930.

For Manufacturers and Importers of Sapphire Substrates

This ruling provides clarity that minor deviations from patent claim limitations, especially those deemed 'substantial,' can prevent a finding of infringement under the doctrine of equivalents, allowing for continued importation of non-infringing products.

For Patent Holders

The decision reinforces the importance of precise claim drafting and the need to demonstrate substantial differences when arguing non-infringement under the doctrine of equivalents. It also highlights the critical requirement of proving a domestic industry for Section 337 actions.
