Over the past decade, the computer software industry has evolved into a critical component of the U.S. Economy. It is presently the fastest growing industry in the United States, with 1992 sales in the three core elements of the software industry -- programming services, prepackaged software and computer integrated design -- accounting for over $36.7 billion of our domestic gross product. The software industry also has created jobs at a remarkable rate; since 1987, employment in the software industry has risen at an annual rate of 6.6 percent and today, the industry employs about 4 percent of the American work force.
The dynamic nature of the U.S. software industry has also served to propel the U.S. firms into a dominant position in the global software industry. U.S. firms hold about 75 percent of the global market for prepackaged software and approximately 60 percent of the world market for software and related services. In 1991, foreign sales of U.S. prepackaged software vendors totaled over $19.7 billion.
Constant innovation has been the key to continued success in the U.S. software industry. As such, it is imperative that our domestic intellectual property systems not only provide an effective stimulus for innovation, but also provide appropriate and effective means for protecting those innovations. Indeed, the continued success of U.S. firms, in both domestic and foreign markets, depends directly on the availability of effective mechanisms to protect software innovations. Without such means, the full value of American innovation cannot be realized.
Intellectual property systems provide the means through which software innovations can be both encouraged and protected. The present framework of intellectual property laws provides three basic forms of legal protection that are most relevant to the development and protection of software; namely, copyrights, patents and trade secret protection. Detailed reviews of each of these forms of protection can be found in the 1992 Office of Technology Assessment report entitled "Finding a Balance: Computer Software, Intellectual Property and the Challenge of Technological Change" (OTA-TCT-527), and in the final report of the Advisory Commission on Patent Law Reform to the Secretary of Commerce (1992). A brief synopsis of these three forms of protection follows.
Software code is protected under copyright law as an original work of authorship. Copyright protection stems automatically from the act of fixation of a work onto a tangible medium. A copyright gives its owner the ability to control the reproduction, adaptation, public distribution, public display and public performance of the software code. Copyrights can be used to prevent others from copying the software program, either through direct duplication or through appropriation of the software's expressive (as opposed to functional) elements. Under U.S. law, copyright owners can also prevent the unauthorized rental of software. Copyright protection cannot be used to prevent the use by others of the functional aspects of software, nor can it be used as a basis for action against independently developed software. In addition, the fair use doctrine under copyright law provides third parties some flexibility in their use of copyrighted works.
Patents can be used to protect processes implemented using software, as well as computer-based systems. The statutory definition of inventions that are eligible to receive patent protection is found in section 101 of title 35, United States Code. This section makes patents available for "any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof." To obtain patent protection, the inventor must apply for protection and proceed through an examination process before the Patent and Trademark Office (PTO). The examination process is used to assess whether the invention for which protection is sought meets all of the statutory criteria for patentability; namely, that the invention is eligible for protection, that it is new, that it is not obvious to a person familiar with the technical field of the invention, and that the invention has been adequately described in the patent application. Patent protection allows the patent holder to preclude others from making, using or selling the patented invention, as it has been defined in the patent claims, for a period of seventeen years measured from the date the patent is granted. Importantly, the party granted a patent must take action to enforce rights provided under the patent--the issuance of a patent does not automatically preclude infringing activity. In addition, the Federal courts have developed a limited exception to liability for infringement for non-commercial experimental use of inventions described in patents. Additional information on the patent process is available in the Manual of Patent examining Procedure (MPeP), in particular, chapters 600, 700 and 2100.
Finally, certain aspects of software can be protected through use of trade secrecy and contractual licensing agreements. Protection of trade secrets in the United States is governed by state, rather than Federal, law. Trade secret laws typically require the party asserting a trade secret right to take reasonable steps to prevent the public disclosure of the information held as a trade secret. Accidental or other public disclosure of a trade secret will eliminate the protection. Absent such disclosure, the trade secret rights will remain effective indefinitely. Trade secret rights can be enforced against parties that unlawfully obtain the information held as a trade secret.
The focus of the discussions in the three scheduled public hearings will be the use of the patent system to protect software-related inventions. There will be three general subject matter areas presented for discussion:
Questions appearing in section II, below, are intended to focus the discussion on each of the topics. They are not intended to discourage individuals from providing written comments on issues they believe should be addressed that are related to the protection of software-related inventions. Written comments on matters not presented below for discussion can be forwarded to the Commissioner of Patents and Trademarks for inclusion in the records of these hearings, but should clearly indicate that the comments are general in nature and not directed at the issues presented for discussion.
II. Topics for Discussion
Topic A. Use of the patent system to protect software-related inventions
The question of patent protection for software-related inventions has engendered a significant amount of public debate. For example, concern has been expressed over the appropriate scope of eligible subject matter (e.g., which aspects of software-related inventions should be eligible for patent protection, and which should not). Others have expressed concerns over the effects of providing protection for inventions in which the main distinguishing characteristic is a software component.
Some guidance on the question of patent eligibility has been provided by the Federal courts. First, the Supreme Court has instructed the lower courts to interpret the eligibility standards for patent protection broadly. In Diamond v. Chakrabarty, 447 U.S. 303, 309 (1980), the Court stated:
Second, the Supreme Court has held that the mere presence of a computer software-implemented mathematical algorithm in an invention does not automatically preclude the invention from being eligible to receive patent protection. Diamond v. Diehr, 450 U.S. 175 (1981). Finally, through interpretation of the exclusions from patentable subject matter under section 101 of title 35, United States Code, the Supreme Court and the lower Federal courts have provided guidance in determining which aspects of software-related inventions are eligible for patent protection.
There are three general categories of exclusions to patent eligibility that are particularly relevant to software-related inventions. The first, and most commonly applied exclusion, is the exclusion of mathematical algorithms, per se, from patent eligibility. For a summary of the law governing this exclusion, and for guidance on how the PTO applies this exclusion in the context of its examination procedures, see "Patentable Subject Matter, Mathematical Algorithms and Computer Programs", 1066 O.G. 5, (Sept. 5, 1989) and "Note Interpreting In re Iwahashi," 1112 O.G. 16 (March 13, 1990). Second, methods of doing business are excluded from patent protection. While no cases have directly applied this exclusion to deny patent protection for software-related inventions, the exclusion is relevant for questioning the patent eligibility of processes that are modeled upon existing business processes but are implemented through a software-based system. See, e.g., Paine, Webber, Jackson & Curtis, Inc., v. Merrill Lynch, Pierce, Fenner & Smith, 564 F. Supp. 1358, 218 U.S.P.Q. 212 (D. Del. 1983). Finally, printed matter, per se, is not eligible for protection under the patent laws. This exclusion has relevance in the context of software code "written" onto non-paper media (e.g., magnetic or optical media capable of storing the software code). See, e.g., In re Miller, 164 U.S.P.Q. 439 (C.C.P.A. 1969); In re Jones, 153 U.S.P.Q. 77 (C.C.P.A. 1967).
Within these limits, however, is a spectrum of inventions whose patent eligibility has been questioned. To encourage discussion of what aspects of software-related inventions should or should not be eligible for patent protection, interested members of the public are invited to offer their views on the following series of questions.
1. What aspects of the following examples of software-related inventions should or should not be protectable through the patent system? [Note--these are generalized hypothetical examples of patent claims. They are not intended to prompt comments as to the merits of the process referred to in the claim (e.g., whether the process is well known or obvious to a computer programmer). Instead, comments are desired as to the benefits or drawbacks of granting patents on the invention defined by the claim, presuming it was new and not obvious to a computer programmer.]
2. What impact, positive or negative, have you or your organization experienced from patents issued on software-related inventions? [Note: If providing comments on this question, please provide details regarding the nature of the impact (e.g., the nature of any action taken by or against you or your organization under a patent, the results of the action, and the impact of those results on your activities or operations).]
3. What implications, positive or negative, can you foresee in maintaining or altering the standards for patent eligibility for software-related inventions (e.g., consider possible effects, if any, on doing business or protecting software products in domestic or foreign markets, conducting research, designing software or modifications thereto, etc.)?
4. Does the present framework of patent, copyright and trade secret law: (a) effectively promote innovation in the field of software? (b) provide the appropriate level of protection for software-related inventions? [Note: If responding to this question, please describe the experiences, if any, that you have had with the current system that led you to your conclusions.]
5. Do you believe a new form of protection for computer programs is needed? If so, what would be the desirable characteristics of such protection (e.g., what would be the substantive requirements for obtaining protection, what procedures would be used to obtain or register rights, what rights would be provided and how would those rights be enforced, and how would the new system relate to existing forms of intellectual property protection)? What would be the drawbacks of a new form of protection?
Topic B. Standards and practices used in examination of patent applications for software-related inventions
Dates and Times for Hearings on Topic B:
Location for Hearing:
Different sectors of the software industry have expressed concern over the ability of the Patent and Trademark Office to examine patent applications for software-related inventions effectively. Much of the discussion involves the lack of availability of printed documents, patents, and other evidence of public use of the invention before the application was filed (e.g., called "prior art") that can be used by examiners as a basis for denying the grant of a patent. Factors that have been identified as contributing to this problem include:
Concerns other than access to and use of prior art have also been cited. For example, some concern has been expressed that the standards used by examiners to assess novelty and/or obviousness over prior art are not reflective of industry standards, with the effect that patents are granted for well-known or obvious software techniques. Others have questioned the closed nature of the examination process, with no public intervention prior to grant, while some have criticized the current options for contesting the validity of granted patents (e.g., the PTO reexamination process or litigation in the Federal courts).
In view of this, the PTO is interested in public input on how to improve the examination process for patent applications for software-related inventions. Interested members of the public are invited to offer comments on the following series of questions:
1. Do patents and printed publications provide examiners with a sufficient and representative collection of prior art to assess novelty and obviousness of software-related inventions? If not, how can existing collections of prior art be supplemented to provide examiners with a complete collection of prior art?
2. Can an accurate measurement of the ordinary level of skill in the art in the field of computer programming be derived from printed publications and issued patents?
3. Should the PTO impose a special duty on patent applicants for software-related inventions to disclose information relevant to their inventions (e.g., one that is higher than in other areas of technology)? [Note: Under current Rule 56 (37 CFR 1.56), all patent applicants are required to disclose to the PTO any information of which they are aware that is pertinent to the invention they claim in their patent application. The standard does not require the patent applicant to search or locate relevant information and present it to the Office for consideration. Failure of an applicant to comply with this requirement can result in the patent being held unenforceable.]
4. Do the standards governing novelty (35 U.S.C. 102) and obviousness (35 U.S.C. 103), as applied by the PTO and the Federal courts, accurately reflect inventive activity in the field of software design and development? [Note: If responding "no" to this question, please provide your suggestions on standards that could be used to demonstrate which software innovations should be viewed as "new" and "non-obvious" to a person of ordinary skill in the field of software design and development.]
5. Should implementing a known process, technique, system or method of doing business on a computer be viewed as being novel and non-obvious if, but for the use of software, the overall process, technique, system or method is well known?
6. In what ways can the PTO change examination procedures to assess novelty and obviousness of software-related inventions? [Note: The following questions are not intended to restrict comments on ways the PTO can improve the examination process, but are offered only as a sample of possible changes to the examination process.
A second topic related to patent examination standards and practices relates to the problem of effectively and meaningfully disclosing software-related inventions in patents and other printed publications. To fulfill their statutorily defined function, patent documents must effectively teach a person of ordinary skill in the relevant field of technology how to make and use the invention that is protected by the patent. With respect to patents on software-related inventions, this means that the patent must disclose enough information to enable the software programmer of ordinary skill to recreate the invention protected by the patent claims. In practice, several concerns have been identified. For example, some have questioned the "disclosure" value of computer program listings that are often included with patent specifications, given the significant administrative problems these listings create for the PTO and the widely divergent manner in which software is written. Others have questioned how best to describe software-related inventions in general, standardized terms (e.g., not through program code listings). In view of these points, the PTO invites public input on the following series of questions regarding disclosure requirements for software-related inventions.
7. What are the most effective ways to describe software (e.g., pseudocode, flowcharts, etc.), and how can they be implemented through the disclosure requirements for patent applications?
8. What difficulties do patent applicants face in complying with existing disclosure requirements (e.g., enablement, description, best mode) for software-related inventions?
9. Should the PTO require patent applicants to conform to a standardized disclosure format for applications filed on software-related inventions?
10. How should the PTO handle the submission of computer program code listings? Should the PTO require submission of program code listings? Should they require submission of code listings in machine readable format only? Should program code listings be included in patent documents or should they be made available only through a publicly accessible database? What hardships would patent applicants face if these requirements were imposed?
11. Are current rules governing the submission of drawings impeding the effective description of software-related inventions, and if so, what changes should be made? [Note: Rule 96 (37 CFR 1.96) governs the submission of computer program listings].
12. What difficulties might patent applicants face if they were required to fully satisfy the disclosure requirements of 35 U.S.C. 112, 1st paragraph (i.e., enablement, description, best mode), without reliance on computer program listings?
Topic C: Significance of and protection for visual aspects of software-related inventions
Date of Hearing for Topic C:
Location for Hearing:
This topic addresses the question of design patent protection for computer screen elements (e.g., icons and other user interface elements), and the significance of screen elements in the context of patentability (utility) of software-related inventions.
Protection of the visual elements of software, particularly computer screen displays and images, is very important to the software industry. Recently, questions have arisen whether design patents can be used to provide protection for such elements. As way of background, a design patent provides protection for only the appearance of an article, not for its structural or utilitarian (functional) features. See, 35 U.S.C. 171. This is in contrast to a "utility" patent that provides protection for new, useful and non-obvious products, processes, machines, and compositions of matter. In the context of software, some have argued that design patents could provide much needed protection for the visual elements of screen displays that give programs their distinctive "look and feel."
The question of design patent protection for computer screen displays or images has been raised in a series of recent cases before the Board of Patent Appeals and Interferences (Board). See, ex parte Tayama, 24 U.S.P.Q.2d 1614 (Bd. PA&I. 1992); ex parte Donaldson, 26 U.S.P.Q.2d 1250 (Bd. PA&I. 1992); ex parte Strijland, 26 U.S.P.Q.2d 1259 (Bd. PA&I. 1992); ex parte Donoghue, 26 U.S.P.Q.2d 1266 (Bd. PA&I. 1992); and ex parte Donoghue, 26 USPQ2d 1271 (Bd. PA&I. 1992). The Board held in each of these cases that screen displays, standing alone, are not statutory subject matter.
The Board concluded that, as claimed and described, the designs were merely pictures, and that "a picture standing alone is not protectable by a design patent." The Board's conclusions are consistent with judicial precedent that treats pictures standing alone as not being statutory design subject matter. This precedent points out that the factor that distinguishes subject matter eligible for design patent protection from a mere picture or surface ornamentation per se (i.e., abstract designs) is "the embodiment of the design in an article of manufacture."
Note that, in dicta, four of the Strijland panel members indicated they would have concluded that statutory subject matter was present if certain threshold requirements were met. These are: (1) the specification as originally filed described and claimed the icon as a design for a programmed computer system; (2) the specification included drawings depicting the icon displayed on the monitor of a programmed computer system and (3) the specification explained how the icon was an "integral and active component in the operation of a programmed computer displaying the design."
The Board decisions leave open the question of the threshold requirements for the protection of screen displays. To assist the Office in evaluating how to proceed in light of these decisions, public comments are invited on the following series of questions:
1. Should design patent protection be available for screen displays and other visual elements of computer software (e.g., should the PTO adopt the suggestion of the Board in the Strijland opinion that, if properly presented, screen displays can be statutory subject matter under 35 U.S.C. 171)?
2. If your answer to 1 is "yes" then:
3. What protection would design patents for screen displays provide that is not already provided by copyright and trademark law?
4. Have you or your organization encountered situations where copyrights or trademarks have failed to provide adequate protection for visual elements of software that could have been addressed through use of design patent protection?
5. Are images displayed on a television screen legally distinguishable from the same image displayed on a computer monitor?
6. Does a description in a specification indicating how a displayed image is an "integral and active component in the operation of a programmed computer displaying the design" provide a workable line between statutory and non-statutory design subject matter?
A second facet of the discussion of visual elements of software is the significance of those elements in evaluating whether a software-related invention is deserving of utility patent protection. Specifically, how should visual elements of a software-related invention be evaluated, in the context of the invention as a whole, during examination and for judicial assessments of validity? The focus of this question is not whether the software-related invention should be eligible for protection under the utility patent law (for discussion of this question, see topic A, above). Rather, it is focused on the significance of visual elements of software in determining whether a patentable improvement has been made to a previously known process or article of manufacture. To assist this discussion, consider each of the following questions in the context of two machines, each having multiple hardware components and one software component that guides the operation of the machine. The only difference between the two machines is that the "new" machine employs different visual display elements in its software component.
7. Should the "new" machine be considered "novel" in view of the different visual elements used in the software component?
8. If viewed as making the machine as a whole "novel", should the visual display elements of the "new" machine justify a conclusion that the product as a whole could be non-obvious to a person of ordinary skill?
9. If you answered yes to questions 1 or 2,
