Credit WoesA Credit Bureau Faces a Decision of Whether to Revise a SystemAnnabelle and Arvin Dorland made an offer on a three-bedroom house in Grande Pointe, New Hampshire. The sellers accepted the offer, and every- thing seemed to be going well. The home was their dream house, with all the features they ever wanted.Jenny Cartier works for First Fiduciary Trust, the bank through which the Dorlands applied for their mortgage. With the Dorlands’ permission, Jenny asked for a credit report from Canyon Credit Company. Canyon is one of three major nationwide credit bureaus.After an uneventful but anxious three days, the Dorlands received a phone call from Jenny at the bank. She said that the credit report from Canyon showed that the Dorlands had an outstanding lien on a fishing boat in Happy Jack, Louisiana. For that reason, the bank couldn’t approve their mortgage application. Arvin was incensed. He told Jenny that there had to be a mistake—that neither he nor Annabelle had ever even visited Louisiana, much less bought a boat there.Jenny replied that if the Dorlands wanted their dream house and a First Fiduciary mortgage, they’d better get the problem cleared up fast. Another couple wanted to make an offer on the house, and the seller wouldn’t wait more than 48 hours. Jenny gave Arvin the name and phone number of Louise Patella, her contact at Canyon Credit.U.S. law allows anyone to get the details of his or her credit report and suggest corrections. Arvin immediately contacted Louise. She researched the problem and discovered another Arvin Dorland, a man from Magnolia, Louisiana. Louise realized that the company had two different Arvin Dorlands on file—the Arvin in New Hampshire was in his mid-30s, while the Arvin in Louisiana was 72. By the time Louise corrected the database and issued a new report to First Fiduciary, the Dorlands’ dream house had been sold to someone else.Arvin and Annabelle’s concern is that the bank will always associate the Dorlands with “that problem with the boat in Louisiana.” Also, they worry that the other two credit companies the bank uses could distribute the erroneous information.Louise’s husband, Peter, also works at Canyon Credit. Peter is the di- rector of systems analysis and design, and he and Louise have often dis- cussed the increasing frequency of complaints concerning incorrect credit reports. After hearing about the Dorlands’ problem, he approached the chief information officer (CIO) of Canyon Credit to suggest a change in the database. Peter argued that the simple coding scheme used to identify a record for retrieval worked fine when the database was small. But now that the database system was large, it needed to be modified so all recordscould be more easily and correctly accessed. Such a change would allow growth to one billion records and eliminate the mistaken-identity prob- lem.The CIO directed Peter to do a full cost-benefit analysis of the matter. Peter discovered that to convert to using unique numeric identifiers would cost over $720,000 and save the company $90,000 per year. Some savings would result from the elimination of claims processing where clients were misidentified. Even larger savings could be realized from reductions in court settlements to those adversely affected by the system’s errors. Peter concluded that the gain in reputation and increased customer satisfaction would be enough to justify the change. The CIO, on the other hand, con- sidered the errors in the database a small problem. Based on the high ini- tial cost and the long payback period shown by the cost-benefit analysis, he was against the change. The dispute was reported to the Information Systems Steering Committee for resolution.Questions :What were some early warning signs that signaled things were not going well with the CityTime project?What steps should city managers and SAIC have taken at an early stage of the project to identify and prevent fraud?Sources:  “CityTime,” New York Times, March 14, 2012,

On February 8, 2013, the Federal Circuit Court of Appeals met to consider a case that could shape the future of technology innovation in the United States. The case involved the Alice Corporation, an Australian company that obtains financial market patents from the United States, the United Kingdom, and other major trading nations.  Alice holds four patents for a business method that CLS Bank International employs to reduce risk in financial transactions. In 2007, Alice sued CLS Bank International and other companies for patent infringement, hoping to reap financial gain. CLS Bank, however, countersued Alice claiming that Alice’s patents were in violation of Section 101 of the Patent Act.Section 101 states that the U.S. government cannot grant patents for “laws of nature, natural phenomena, and abstract ideas.”  Rather, patents must involve only practical applications of abstract ideas. But what is the difference between an abstract idea and a practical application? The answer to this question involves high stakes—billions of dollars in the IT industry.Many lawyers who represent IT companies describe patent-enforcing companies (such as Alice Corporation) as “patent trolls.” Such companies do not produce a product themselves. Rather patent trolls make money by threatening to sue technology companies that supposedly make use of their patented ideas. The patent troll is usually not the inventor, but rather a company that has purchased patents from bankrupt technology companies, usually failed start-ups. Patent trolls generally target companies with annual revenues between $50 and $200 million. These companies are large enough to pay licensing fees, but often lack resources to pay steep litigation fees.For example, a company called Ultramercial obtained a patent for the idea of “pre-roll advertisements”—ads placed prior to the broadcasting of free video clips broadcast on YouTube and Hulu. These ads are a major revenue source for YouTube, Hulu, and other companies. One of these companies, Wild Tangent, sued Ultramercial asserting that its patent claim was invalid; however, an appellate court upheld a lower court’s ruling declaring the patent valid.  In the summer of 2012, the Supreme Court issued a ruling in the case asking the appellate court to reconsider its ruling, which, if not overturned, would force companies such as YouTube and Hulu to pay large licensing fees to Ultramercial.According to Google general council Kent Walker, “Abuses of our patent system cost the economy $29 billion in 2011, raising prices and reducing choice. Technology moves incredibly fast, and the United States Patent and Trademark Office need to take prompt action.”Software patents were not even recognized by U.S. Courts until the States Street case of 1998. Up to that point, many companies had patented software ideas for business methods, but none of the patents had been enforced.  In 1998, the U.S. Court of Appeals recognized Signature Financial Group’s patent of a business method using computers and allowed the company to collect licensing fees from States Street Bank.Since the States Street decision, the U.S. court system has been floundering with the issue. Different courts have come down on different sides. In the earlier appellate hearing of the Alice case, two judges of the three-judge panel held for Alice Corporation and argued for an extraordinarily broad interpretation of patent law. Now, most of the heavyweights of the U.S. IT sector—Google, IBM, Facebook, Intel, and others—have filing amicus briefs, legal opinions in support of one side or the other. IBM, which has led the world in number of new patents for 21 years, filed a brief in support of Alice. Google and Facebook, which are leading product producers, filed in support of CLS Bank. Intel, a computer chip manufacturer that has many patents but is fearful of the large number of patents in the field of theoretical chip design, also filed on the side of the bank.The new appellate court decision will likely pave the way for the Supreme Court to weigh in on the matter more extensively. A decision in favor of Alice would mean an explosion of patent litigation and increase in costs for IT producers. A decision against Alice would be a boost for large IT software manufacturers and creators on online content and products who may be less careful about paying licensing fees to small patent holders. The Department of Justice has filed an amicus brief favoring neither side. Instead, the department has called on the appellate court not to issue a decision that would create a hard-and-fast rule, but that would allow the courts to consider each case individually.  This action indicates that the U.S. government feels that both positions have some merit. On the one hand, patent trolls are reducing U.S. productivity. On the other hand, the Department of Justice recognizes the need to protect the owners of intellectual property.(The length of your answer should be from roughly four or five sentences to a couple of paragraphs for each questions listed below).How unique does an idea need to be to warrant patent protection? Should the idea of pre-roll advertisements be patentable?Are patent trolls justified in their actions? Do they provide a means of rewarding small innovators?Are patent lawsuits likely to decrease or increase innovation in the United States?
