                   September 28,199O

                   The Honorable Ron Wyden
                   Chairman, Subcommittee on Regulation,
                     Business Opportunities, and Energy
                   Committee on Small Business
                   House of Representatives

                   Dear Mr. Chairman:

                   As requested in your April 4, 1990, letter, and subsequently agreed with
                   your office, we updated our report on the large backlog of unprocessed
                   biotechnology patent applications at the U.S. Patent and Trademark
                   Office (POD),an agency of the Department of C0mmerce.l That report
                   dealt with several issues, including: the level of scrutiny required to pro-
                   cess these applications compared to others; actions taken to streamline
                   the process for these applications; and the ability of P?Dto attract and
                   retain qualified examiners.

                   In this update, we determined (1) the extent of the current backlog, (2)
                   the current impact of m actions to accelerate decisions on biotech-
                   nology patents, and (3) the impact of continuations on reported patent
                   pendency time in 1989. We briefed your staff on the results of our work
                   on July 13, 1990, and, as requested, have summarized the information in
                   this report.

                   The swift granting of a patent encourages both investment in biotech-
Results in Brief   nology research and the commercialization of related inventions. Unfor-
                   tunately, despite p1~ actions designed to accelerate decisions on
                   biotechnology patents, processing delays continue for a growing backlog
                   of biotechnology patent applications.

                   During calendar year 1989 and the first half of 1990, the inventory of
                   unexamined biotechnology patent applications increased by about 33
                   percent, from about 6,200 to about 8,200. This increase reflects about a
                   15percent average annual increase in the number of filings during the
                   past 6 years. Over 40 percent of the about 8,200 backlogged patent
                   applications were over 12 months old.

                   Page 1                                                      GAO,‘RCED-go-231   Biotechnology

             PTO’Sefforts to accelerate the award of biotechnology patents have been
             less effective than anticipated, The average waiting time for processing
             biotechnology patent applications was about 26 months in 1989 com-
             pared with the about 1Qmonth average for all other technologies.
             Because of the large growth in filings and the shortage of experienced
             senior biotechnology patent examiners, P’IDis no longer projecting that
             by 1992 it will reduce the pendency period for biotechnology patents
             from its current 26-month average to the targeted 18-month average
             goal for all patent applications. As of August 1990, PKI had not estab-
             lished a new date to replace the 1992 target date.

             The actual time required to process inventions contained in patent appli-
             cations is longer than the pendency reported by the P?Dbecause the PT~
             measures pendency of applications, not inventions. A patent granted on
             an invention may be the result of a chain of replacement applications, or
             continuing applications. For example, during 1989, about one-third of
             the 26,616 inventory of unexamined (backlogged) and in process bio-
             technology patent applications resulted from chains of continuing appli-
             cations. Factoring in the original application date for the 7,079 patent
             applications issued or abandoned in 1989 would add 9.0 months to P?D’s
             reported average patent pendency of 26.3 months.

             Patent applications are assigned to the appropriate examining group-l
Background   of 16 such groups. Each group includes a number of suborganizations,
             art units, responsible for a specific area of technology. Examiners in the
             art units review patent applications to decide whether the inventions
             described are entitled to patent protection.

             The examination process includes a search through United States pat-
             ents, prior foreign patent documents that are.available in p1~, and avail-
             able nonpatent literature, to see if the invention is new, useful and
             nonobvious (significantly different from prior inventions). The exam-
             iner decides whether to grant a patent based on a review of the applica-
             tion and search results.

             An Office “action” notifies the applicant of the examiner’s decision. It
             states reasons for any adverse decision or any objection or requirement
             and provides information that may assist the applicant in judging
             whether to pursue the application. If the invention is not considered pat-
             entable subject matter, the claims will be rejected. Some or all of the
             claims may be rejected on the first action by the examiner; relatively
             few applications result in patents as originally filed.

             Page 2                                          GAO/RCED-!XJ-231   Biotechnology

                           If the application is rejected or objected to, the applicant must request
                           reconsideration in writing, responding to every rejection in the Office
                           action. The application is then reconsidered, and the applicant is again
                           notified of the Office’s decision. If the applicant elects not to further
                           pursue the issuance of a patent under the existing application, P?Dcon-
                           siders the application as no longer pending and classifies it as aban-
                           doned. In order to control the time frame of patent applications, P?D
                           normally makes the second Office action final. The applicant is then lim-
                           ited to: (1) appeal to the P?DBoard of Patent Appeals and Interferences
                           and to the courts in the case of rejection of any claim; (2) presentation of
                           a further amendment for consideration by the examiner (although the
                           applicant does not have a right to have the amendment entered by the
                           examiner); or (3) filing a continuing application.

                           As an alternative to appeal, when applicants desire consideration of dif-
                           ferent claims or of further evidence, continuation applications are often
                           filed. Each continuing application also needs to include the claims and
                           evidence for which consideration is desired. If the continuing applica-
                           tion is filed before expiration of the appeal period and it refers specifi-
                           cally to an earlier application, the applicant is entitled under 35 U.S.C.
                           120 to the date of the earliest filed application for subject matter
                           common to both applications.

                           An earlier filing date is important because occasionally two or more
                           applications are filed by different inventors claiming substantially the
                           same patentable invention. The earlier filing date determines patent
                           rights, absent any other evidence. Furthermore, in the examining group,
                           applications are examined in the order in which they have been filed.
                           Thus, continuing applications are scheduled for examination based on
                           the date of an earlier filed application on which they rely for common
                           subject matter.

                           The number of unexamined biotechnology patent applications continues
    Backlog Continues to   to increase. Between January 81989, and July 3, 1990, the number of
    Grow                   biotechnology patent applications not yet acted upon increased from
                           6,163 to 8,213 (41.3 percent of which were over 12 months old). One
                           contributing factor is that the filing of biotechnology applications has
                           grown at a significantly higher average annual rate-14.9 percent-
                           than have all patent applications -7.6 percent-during      fiscal years
                           1984 through 1989.

                       As we reported in April 1989, PTOinstituted a 13-point plan in 1988 to
Long Delays Continue   accelerate the award of biotechnology patents. The plan includes hiring
Despite New Efforts    100 new biotechnology patent examiners over 6 years, consolidating all
                       biotechnology examining responsibilities into a new group (called -
                       “Group ISO”), which currently contains eight art units, enhancing
                       search tools by using personal computers to access PTDand commercial
                       data bases, improving training for examiners by joining with the bio-
                       technology industry to create the Biotechnology Institute, and liberal-
                       izing the procedure for requesting accelerated examination.

                       Through June 30,1990, the number of biotechnology patent examiners
                       assigned to Group 180 increased by 23 percent (from 91 to 112) from
                       October 1,1988. According to the P?D,more biotechnology patent exam-
                       iners would have been hired, but it had an insufficient number of expe-
                       rienced senior staff to train them. Only 16 of the current 112
                       biotechnology examiners (14 percent) have more than the 6 years’ expe-
                       rience required to become a senior examiner.

                       The large number of patent applications not yet acted upon, along with
                       the relatively small number of experienced senior examiners, have con-
                       tinued to cause long waiting periods for PTOfirst actions. During cal-
                       endar year 1989 and the first half of 1990, first actions in the
                       biotechnology area were made an average of 13.1 months after the filing
                       date of the application, whereas first actions in all technologies aver-
                       aged 7.1 months after the filing date of the application.

                       To avoid the wait created by the backlog, PTOhas developed accelerated
                       examination procedures, which allow applicants who can justify their
                       need for expedited processing to have their applications reviewed before
                       others, regardless of the filing date. However, very few biotechnology
                       patent applicants have taken advantage of this special status. Our anal-
                       ysis of Patent Application, Location, and Monitoring (PALM) computer-
                       ized data showed that of 26,616 biotechnology patent applications
                       pending during 1989, only 144 had petitions for accelerated examina-
                       tion. (See table 1.9.) In April 1989, we reported that applicants are reluc-
                       tant to use the accelerated procedures because of perceived legal risks.

                       Page 4                                           GAO/RCFtD-DO-231   Biotechnology

                       Because of the size and age of the backlog created by the large growth in
                       filings and the shortage of experienced senior biotechnology patent
                       examiners, p1~ no longer believes it can meet its goal of reducing the
                       average biotechnology patent processing time from its 26-month
                       average to 18 months by 1992, bringing the pendency for these patents
                       in line with the pn> average for all technologies. No new target date had
                       been established as of August 1990.

                       As we previously reported, PTOmeasures pendency of each application
Extensive Use of       in a chain of replacement applications, or continuing applications. PTO
Continuations Masks    officials believe that measuring pendency of applications rather than of
Actual Pendency Time   inventions is a better management control over patent processing effi-
                       ciency because patent examiners cannot control the use of continua-
                       tions. Only the patent applicant decides whether and when to file a
                       continuing application, so long as it is filed during the pendency of the
                       prior application.

                       A continuing application is often filed in situations where an applicant
                       desires consideration of different claims or of further evidence related
                       to an application for an invention considered unpatentable and rejected
                       by a PTO examiner. With a continuing application that meets the condi-
                       tions of 35 USC. 120, the applicant is entitled to the benefits of the
                       earlier filing date of the prior application. This earlier date may be
                       important in determining patentability or who owns an invention,
                       although pendency is measured from the latest filing.

                       Using PALM data, we determined that about 32 percent of the 26,616 bio-
                       technology patent applications pending during 1989 resulted from con-
                       tinuations. (See tables I. 1 through 1.4.) We did not examine the extent of
                       the use of continuations by applicants in other technologies, but EYIDoffi-
                       cials told us that continuations for all technologies is 24 percent.

                       We used the date of the original application rather than the date of the
                       most recent continuation application for the 7,079 patents issued or
                       abandoned in 1989 and calculated pendency of 36.3 months-Q.0
                       months more than the m-reported average patent pendency of 26.3
                       months. (See tables I.5 and 1.6.) Using this same approach, we calculated
                       that the 18,634 applications pending at the end of 1989 had, on average,
                       been in process for 26.7 months since their original application date.

                       Page 5                                           GAO/BCED-9@231   Biotechnology




These 18,534 applications included 7,529 unexamined (backlogged)
applications (examiners had not yet made a first Office action). (See
table 1.7.) A total of 1,627 of the patent applications pending at the end
of 1989 had been in process for more than 5 years since the date of the
original application.

The pTDpendency goal for patent applications is 18 months. Thus, if the
original application date was considered, the 18,634 patent applications
pending at year-end had already been in process, on average, about 50
percent more than the pendency goal. However, according to PRI offi-
cials, the pendency goal would be more than 18 months if P?Dmeasured
pendency of inventions rather than of applications.

Our analysis of the recorded processing steps for 926 biotechnology
patent applications (with a first Office action) abandoned and refiled as
continuation applications in calendar year 1989 showed that an average
of 2.5 Office actions and 31.2 months elapsed during the life of the orig-
inal application. About 25 percent were abandoned after the first Office
action, and an additional 50 percent received a final rejection after the
initial response from the applicant. A final rejection after the applicant’s
first response is counted as the second Office action by PID. About three-
quarters of the 595 final rejections were second Office actions. This
rejection rate is consistent with pm’s policy of normally making the
second Office action final. Only about a fifth of the 926 applications had
more than 2 Office actions. (See table 1.8.)

Our audit work was performed between April and July 1990 in accor-
dance with generally accepted government auditing standards. Our
review included an analysis of PALM data contained in m computer
tapes for all biotechnology patent applications on hand during 1989. We
also examined work load reports generated during 1989 and the first 6
months of 1990 by n’ro. Appendix I contains tables of data generated
from our analysis of PALMcomputer tapes.

We discussed this report’s contents with PTO officials, who concurred
with the facts, and their comments have been included where appro-
priate. As agreed with your office, however, we did not obtain official
agency comments on this report. As arranged with your office, unless
you publicly announce its contents earlier, we plan no further distribu-
tion of this report until 14 days from the date of this letter. At that time,
we will provide copies of this report to the Department of Commerce
and to others upon request. If you have any further questions on these
