B.E. Technology v. Google — Delaware Court Invalidates Last Targeted Advertising Patent Claim Under §101

Background

B.E. Technology, L.L.C. filed this patent infringement suit against Google in May 2020, asserting three patents covering methods of reactive targeted advertising. Two of those patents—U.S. Patent Nos. 8,549,410 and 8,549,411—were knocked out through inter partes review (IPR) proceedings at the USPTO. That left Claim 25 of U.S. Patent No. 8,769,440 (the “‘440 Patent”) as the sole surviving claim.

The ‘440 Patent is titled “Method of Reactive Targeted Advertising.” The asserted Claim 25 (which depends from base Claim 1) covers, in essence: a software-based method that (1) permits users to access servers; (2) transfers software to users’ computers to display ads and record computer usage data; (3) determines a unique identifier for each computer; (4) selects targeted ads based on that identifier; and (5) delivers real-time reactive targeted advertising based on user interaction with the computer.

The case had significant procedural history. As early as December 2020, then-Judge Leonard Stark (now a Federal Circuit judge) ruled that the claims were directed to the abstract idea of “providing real-time targeted advertising based on keywords on web pages visited by a user.” B.E. was allowed to amend its complaint and later moved for summary judgment arguing patent eligibility; Google cross-moved for summary judgment of ineligibility under 35 U.S.C. §101.

The Court’s Holding

Judge Williams applied the two-part Alice/Mayo framework and granted Google’s motion for summary judgment, holding Claim 25 patent-ineligible. At Alice Step One, the court found the claim directed to the abstract idea of “providing real-time targeted advertising based on information known about a user”—a fundamental practice analogous to a television channel choosing which commercial to air based on the time of day, or a salesperson tailoring a pitch in real time. The court drew on a long line of Federal Circuit decisions including Intellectual Ventures I v. Capital One Bank, Customedia Technologies v. Dish Network, Free Stream Media v. Alphonso, and Broadband iTV v. Amazon, all of which found similar targeted-advertising claims abstract.

At Alice Step Two, the court examined each element B.E. argued provided an inventive concept and rejected them all. The “transferring” limitation—sending software to users’ computers to collect usage data—was disclosed in prior art systems described in the patent’s own specification. The “determining” and “selecting” limitations were routine data-collection and ad-selection steps insufficient to transform the abstract idea. The “real time” limitation—unique to Claim 25—likewise failed because performing a mental process faster using conventional computers is not an inventive concept. Finally, the ordered combination of all elements merely restated the abstract idea without adding anything inventive.

Key Takeaways

• A patent directed to internet-based targeted advertising, even with a “real time” limitation, is an abstract idea under Alice Step One—courts have consistently analogized such methods to familiar offline advertising practices like tailoring TV commercials or sales pitches.
• At Alice Step Two, the inventive concept must be evident in the claim language itself; a patentee cannot save an abstract claim by pointing to improvements disclosed in the specification that are not expressly required by the claims.
• Adding “real time” processing to an otherwise-abstract targeted advertising method is insufficient to supply an inventive concept, particularly where the patent’s own specification acknowledges that prior art systems already performed reactive advertising.
• B.E.’s reliance on prior representative-claim findings—despite arguing those findings should no longer apply after related claims were IPR’d—was rejected under the law-of-the-case doctrine.

Why It Matters

This decision ends a six-year patent dispute that once threatened Google’s core advertising business. For B.E. Technology, which had already lost the ‘410 and ‘411 patents in IPR, Claim 25 of the ‘440 Patent was the last remaining avenue for recovery. The ruling illustrates the enduring difficulty of patenting Internet advertising methods: courts have repeatedly found that using computers and networks to do what advertisers and salespeople have always done—tailor messages to audiences—is an abstract idea, no matter how specific the technical implementation described in the specification.

For patent practitioners, the decision reinforces a critical drafting lesson: the inventive concept at Alice Step Two must be captured in the claim language itself, not merely described in the specification. Patentees who rely on embodiments in the spec to supply inventiveness, but whose claim language covers broader, more generic implementations, face a serious eligibility gap that courts will not bridge.
