Obviousness Analysis of US Patent 8,069,073

Standard for Obviousness (35 U.S.C. § 103)

Under United States patent law, an invention is considered obvious if the differences between the invention and the prior art are such that the invention as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art (PHOSITA). An analysis of obviousness typically involves determining the scope of the prior art, identifying the level of ordinary skill in the art, and assessing whether the prior art would have motivated a PHOSITA to combine existing elements to arrive at the claimed invention with a reasonable expectation of success.

The priority date of the '073 patent is December 23, 1999. The relevant PHOSITA would be an individual with knowledge of computer science, database management, and marketing research techniques, including preference elicitation and analysis methods prevalent in the late 1990s.

Core Inventive Concept of the '073 Patent

The central claim of the '073 patent is the creation of a bilateral preference matching system using a specific methodology. The key claimed elements are:

1. A computerized system involving a "party" and a "counterparty."
2. Supplying forced-choice questions to both sides of a transaction.
3. Generating a preference profile for both sides using conjoint analysis.
4. Comparing the two profiles to determine a "closeness-of-fit" and delivering a ranked match list.

The patent's asserted innovation is not the creation of conjoint analysis or online matching platforms, but the symmetrical application of conjoint analysis to both parties in a transaction to create a more nuanced, two-way match.

Primary Combination of Prior Art Rendering the Claims Obvious

The claims of US patent 8,069,073 are rendered obvious by the combination of U.S. Patent 6,029,195 (the '195 patent) in view of U.S. Patent 5,970,475 (the '475 patent).

1. Base Reference: U.S. Patent 6,029,195 A ('195 patent)

• What it Teaches: The '195 patent discloses the foundational framework of the '073 invention: a bilateral matching system implemented on a computer network. It explicitly describes a marketplace where both a buyer (the "party") and a seller (the "counterparty") can input their respective product attributes and requirements. A central "matching engine" then compares the inputs from both sides to facilitate a transaction. This reference squarely establishes a two-sided matching process.
• What it Lacks: The '195 patent's matching engine operates on simple, explicitly stated "specifications" and "requirements" (e.g., price range, color). It does not teach the more sophisticated method of using "forced choice questions" and "conjoint analysis" to derive deeper, underlying preference profiles that account for trade-offs.

2. Secondary Reference: U.S. Patent 5,970,475 A ('475 patent)

• What it Teaches: The '475 patent provides the missing element. It discloses a computer-aided system for helping a user make a selection from alternatives based on multiple attributes. Crucially, it describes a process for eliciting a user's preferences and relative importance for each attribute to calculate a utility score for each alternative. The patent's own description states this method is "consistent with the principles of conjoint analysis." It therefore teaches the precise preference elicitation and analysis engine claimed in the '073 patent.
• Limitation: The system described in the '475 patent is unilateral. It is a decision-support tool for a single user (the "party") to evaluate a set of passive alternatives (the "counterparties").

3. Motivation to Combine

A person of ordinary skill in the art in 1999, when presented with the bilateral matching system of the '195 patent, would have recognized its primary limitation: the rigidity of matching based on explicit specifications. Such systems fail to capture the nuances of preference, such as a user's willingness to trade a less important attribute for a more important one (e.g., accepting a higher price for a much better product). This limitation presents a clear problem to be solved: how to improve the quality of matches in a bilateral system.

The '475 patent was a known solution for creating more sophisticated preference models. Its conjoint-style analysis was designed specifically to overcome the limitations of simple checklists by uncovering the underlying utility values and trade-offs a person assigns to different attributes.

A PHOSITA would have been motivated to combine the teachings of the '475 patent with the framework of the '195 patent for the predictable purpose of achieving better matches. The logic is straightforward:

1. Start with the two-sided matching system of the '195 patent.
2. Improve the primitive data input method ("specifications") by replacing it with the advanced preference elicitation method ("conjoint analysis") taught by the '475 patent. This would be applied first to the "party" (buyer) side.
3. Apply Symmetrically: Given that the '195 patent establishes a symmetrical marketplace where both parties are active participants, it would have been an obvious and logical step to apply the same advanced preference modeling to the "counterparty" (seller) side. In any two-sided market (e.g., employment, partnerships), both sides have complex preferences. An employer's preference for a candidate is just as nuanced as a candidate's preference for a job.
4. Result: The result of this combination is a system where both a party and a counterparty answer forced-choice questions; a conjoint-based preference profile is generated for each; and the profiles are compared. This combination directly arrives at the invention claimed in US 8,069,073. The expectation of success would have been high, as it involves applying a known analysis technique to a known system to achieve a predictable improvement.

Conclusion

The claims of US patent 8,069,073 would have been obvious to a person of ordinary skill in the art at the time of the invention. The '195 patent established the concept of a bilateral matching system, and the '475 patent taught the use of conjoint analysis to create detailed preference profiles. Combining these two references to create a bilateral system with more sophisticated preference analysis on both sides represents a predictable and logical step to improve the functionality of the base system. Therefore, the patent is obvious under 35 U.S.C. § 103.
