An analysis of U.S. Patent No. 6,076,733 ("the '733 patent") has been conducted to assess the patentability of its claims in light of the prior art of record, specifically concerning the non-obviousness requirement under 35 U.S.C. § 103. The '733 patent, filed on April 25, 1997, claims a system and method for accessing World Wide Web (WWW) documents by scanning a barcode encoded with a Uniform Resource Locator (URL).

The standard for obviousness, as defined in 35 U.S.C. § 103, is whether the differences between the claimed 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). This analysis requires a factual inquiry into the scope of the prior art, the differences between the prior art and the claims, and the level of ordinary skill in the pertinent art. A key component is determining whether a PHOSITA would have been motivated to combine prior art teachings to arrive at the claimed invention with a reasonable expectation of success.

A person of ordinary skill in the art at the time of this invention (mid-to-late 1990s) would likely have been a software developer or computer engineer with experience in data input peripherals (like barcode scanners) and emerging internet technologies, including web browsers and network protocols. Such a person would be aware of the increasing use of the World Wide Web and the common methods for navigating it, as well as the established use of barcodes for rapid and accurate data entry in various industries.

The independent claims of the '733 patent can be rendered obvious by combining existing prior art references. The following combinations demonstrate that the claimed invention represents a predictable combination of known elements to solve a known problem.

Combination of Prior Art Rendering Claims 1 and 11 Obvious

Primary Reference: U.S. Patent No. 5,804,803 ("the '803 patent")
The '803 patent, filed in January 1996, teaches a system that uses a barcode scanner as a universal interface for a computer. It discloses the concept of a scanned barcode representing various commands or data that the computer can then interpret to perform specific actions, such as launching an application or inputting text. This establishes the foundational principle of using a barcode to automate computer functions beyond simple data entry.

Secondary Reference: The state of the art of the World Wide Web in 1997
By early 1997, the World Wide Web was experiencing explosive growth. GUI-based web browsers like Netscape Navigator and Microsoft Internet Explorer were common, and the use of URLs to access specific web pages was a fundamental and widely understood concept. Manually typing URLs into a browser's address bar was the standard method of navigation, a process known to be tedious and prone to error, especially with longer URLs.

Motivation to Combine:
A person of ordinary skill in the art, aware of the '803 patent's teaching of using barcodes to automate computer commands, would have been motivated to apply this method to the increasingly common task of web navigation. The problem to be solved was the inefficiency and inaccuracy of manually typing URLs. The '803 patent provides the solution of automated data input via barcode scanning. The motivation to combine these elements would have been to improve the user experience by making web navigation faster and more reliable. It would have been a natural and predictable step to encode the URL string—the very data a user was typing—into a barcode and use the system taught by the '803 patent to input this data directly into the web browser's address field, thereby automating the process of navigating to a website. The result would be the system described in claim 1 and the method in claim 11 of the '733 patent. This combination of familiar elements according to known methods yields a predictable result, which is a strong indicator of obviousness.

Alternative Combination of Prior Art for Claims 1 and 11

Primary Reference: U.S. Patent No. 5,128,525 ("the '525 patent")
The '525 patent, issued in 1992, describes a method and apparatus for automatically identifying and inputting data into a computer using a hand-held scanner and barcodes. This patent establishes the core concept of replacing manual keyboard entry with barcode scanning for efficiency and accuracy.

Secondary Reference: U.S. Patent No. 5,591,956 ("the '956 patent")
The '956 patent, filed in March 1995, discloses a remote control with an integrated barcode scanner used to navigate a television by scanning codes from a printed guide. This reference teaches the application of barcode scanning to navigate a content system (television programming) by using a physical guide as the source of the navigation data.

Motivation to Combine and Modify:
A person of ordinary skill in the art would see the parallel between navigating television channels via a printed guide and navigating web pages via a printed directory of websites. The '956 patent teaches using a barcode to select content from a guide. The '525 patent teaches the general utility of using barcodes for data input into a computer. With the rise of the internet, it would have been obvious to adapt the content navigation concept of the '956 patent from the television domain to the internet domain. This would involve replacing the channel-selection data in the '956 patent's barcodes with URL data and targeting a web browser on a computer (as in the '525 patent) instead of a television tuner. The motivation would be to provide the same convenience for internet users that the '956 patent provided for television viewers—a quick and easy way to access desired content from a printed list. This combination directly suggests the system and method of claims 1 and 11.

Combination of Prior Art Rendering Claim 21 Obvious

Primary Reference: U.S. Patent No. 5,971,277 ("the '277 patent")
The '277 patent, with a filing date of May 13, 1997, which is after the '733 patent's filing date, would not be considered prior art. However, the previously provided analysis of this patent is useful for context. A more appropriate reference is U.S. Patent No. 5,245,165, which describes a system for tracking objects (items for order) using bar code labels.

Alternative Primary Reference: U.S. Patent No. 5,245,165 ("the '165 patent")
The '165 patent, issued in 1993, discloses a system for ordering items from a catalog by scanning a barcode associated with each item. This barcode contains unique item information which is transmitted to a central system. This establishes the concept of linking a physical item to a unique electronic record via a barcode for tracking and transactional purposes.

Secondary Reference: The state of the art of the World Wide Web and databases in 1997
By 1997, it was well-known to use the World Wide Web to access information stored in databases. HTML forms and server-side scripting allowed users to query a database through a web browser and view the results. The concept of a unique identifier (like a product number or a primary key in a database) to retrieve a specific record was fundamental to database management.

Motivation to Combine:
A person of ordinary skill in the art would have been motivated to combine the physical-to-digital linking concept from the '165 patent with the capabilities of a web-based database. The problem was how to efficiently access information about a specific physical object (like a document) using a networked system. The '165 patent shows using a barcode as a unique identifier for a physical item. The state of the art at the time showed that web browsers could be used as universal clients to access database information. The obvious solution was to use the barcode to encode not just any identifier, but a URL that directly points to the database record for that specific object. This would allow anyone with a scanner and a web browser to immediately access information about the object, which is precisely the invention of claim 21. The motivation is clear: leveraging the new, ubiquitous infrastructure of the web to improve upon existing barcode-based tracking and information retrieval systems, making them more accessible and powerful.

Conclusion

The independent claims of the '733 patent appear to be obvious in light of prior art. The core concept of scanning a barcode to input a URL into a web browser is a predictable combination of a known data-entry technology (barcode scanning) with a prevalent application (web navigation). Similarly, applying this concept to document tracking by linking a physical item to a web-based database record via a URL-encoded barcode would have been an obvious improvement over existing tracking systems to a person of ordinary skill in the art in 1997. The motivation to combine the cited references stems from a clear and recognized need to simplify and expedite interaction with the burgeoning World Wide Web.
