Ottah v. Verizon Services Corp.

Background

Chikezie Ottah, proceeding without a lawyer, sued Verizon Services Corp. for patent infringement. Ottah is one of three co-inventors of United States Patent No. 7,152,840, which concerns a removable book holder for use in a mobile structure such as a vehicle, wheelchair, walker, or stroller. Ottah alleged that a device in a Verizon company vehicle infringed the patent. Verizon identified the device as a Jotto Desk Universal Laptop Mount.

The patent’s single claim requires, among other things, a clasp that allows the book holder to be removably attached. The accused product uses a metal base that must be installed on the vehicle floor with tools and self-tapping screws. Verizon initially moved to dismiss. The court later converted that motion into a motion for summary judgment under Federal Rule of Civil Procedure 12(d), giving both sides an opportunity to submit additional evidence and legal arguments.

Standing Issue

In a footnote, the court rejected Verizon’s argument that the case should be dismissed for lack of subject-matter jurisdiction because Ottah was not the patent’s sole owner. The court found that the co-inventors’ affidavits, interpreted liberally, showed their intent to give Ottah the unilateral right to sue for infringement and to waive their own rights to do so in the future.

Summary-Judgment Standard

Summary judgment is appropriate when the evidence shows that there is no genuine dispute about any important fact and the moving party is entitled to judgment under the law. Although the same standard applied, the court gave special consideration to Ottah’s submissions because he was representing himself.

Literal Infringement

The court held that no reasonable jury could find literal infringement. Patent infringement requires the court to determine the meaning and scope of the patent claims and then compare the properly interpreted claims with the accused device. For literal infringement, the accused device must contain every limitation of the claim.

The court determined that the patent’s plain language and specification required a clasp that permitted removable attachment. The accused product did not have such a clasp and instead was designed to be permanently affixed to the vehicle floor with screws and tools. The court rejected Ottah’s argument that the patent covered other attachment methods, reasoning that accepting that argument would eliminate the claim’s removable-clasp limitation. Verizon was therefore entitled to summary judgment on literal infringement.

Doctrine of Equivalents

The doctrine of equivalents can impose liability when a product does not literally satisfy a patent claim but performs substantially the same function in an equivalent way. The court held that no reasonable jury could find infringement under that doctrine either.

The court applied prosecution-history estoppel, a rule that prevents a patent owner from later claiming subject matter surrendered while obtaining the patent. During the patent-application process, Ottah emphasized removability and attachment without tools to distinguish the invention from earlier technology. The court concluded that Ottah could not later claim that the accused product’s permanent, tool-based attachment was equivalent to the patent’s clasp-based, tool-free attachment. The court also stated that, even if Ottah argued that the amendment was not intended to narrow the claim, he could not invoke the doctrine of equivalents because his explanation showed that he knew about other attachment methods when applying for the patent.

Disposition

The court granted Verizon’s motion for summary judgment. The Clerk of Court was directed to mail the opinion to Ottah and close the docket entry and the action.
