Because the article gives you only the titles, I'm supplying the abstracts from the patents here. If you would like to read the full text of the patents, they are available online from the search pages of the United States Patent and Trademark Office. You can use the patent numbers I've listed below to find the full text of the patents.
The abstract from the first patent, # 5,576,951, an "Automated sales and services system:"
A system for composing individualized sales presentations created from various textual and graphical information data sources to match customer profiles. The information search and retrieval paths sift through a hierarchy of data sources under multiple operating programs. The system provides the means for synergistically creating and displaying customized presentations in a convenient manner for both the customer and salesperson to achieve a more accurate, efficient and comprehensive marketing presentation. Organizational hierarchies of data sources are arranged so that an infinite number of sales presentation configurations can be created. Multiple micro-programs automatically compose the sales presentations initiated by determinants derived from customer profile information, sales agent assessment data and operator's entries including the retrieval of interrelated textual and graphical information from local and remote storage sources. A similar system can be used for filing applications with an institution from a plurality of remote sites, and for automatically processing applications in response to each applicant's qualifications. Each multimedia terminal comprises a video screen and a video memory which holds co-related image-and-sound-generating information arranged to simulate the aspect and speech of an application loan officer on the video screen. The simulated loan officer is used to acquire personal loan data from the applicant by guiding him through an interactive sequence of inquiries and answers.The second patent is 3 6,289,319 , an "Automatic business and financial transaction processing system:"
A system for filing applications with an institution from a plurality of remote sites, and for automatically processing said applications in response to each applicant's credit rating obtained from a credit reporting service comprising a series of self-service terminals remotely linked via a telephone line to a first computer at the institution and to a second computer at the credit reporting service headquarters. Each remote terminal comprises a video screen and a video memory which holds image-and-sound-generating information arranged to simulate the aspect and speech of an application loan officer on the video screen. The simulated loan officer is used to acquire loan request data from the applicant by guiding him through an interactive sequence of inquiries and answers. The terminal is programmed to acquire credit rating data relating to the applicant from the credit rating service, and to use the data to compute the credit worthiness of the applicant and the amount which may be loaned to him. The approved loan information is then transmitted to the first computer for further processing by the financial institution.These abstracts seem like they would only apply in limited cases, rather than for millions of web sites. Both appear to only involve the issuance of loans, rather than a much broader interpretation applying to the sale of goods and services over the world wide web. But, it will be a court that ultimately decides how broadly or narrowly Pangia's patents apply.
