The petroleum industry i s a complex and fascinating business. It deals with a finite natural resource which most of us take for granted. We've always lived in the age of oil and it's d i f f i c u l t for us to imagine any other way of life. When you think of the oil business, what comes to mind? Probably oil wells, pipelines, tankers, oil refineries, petrochemicals plants, and service stations. The oil business is all this and much more. An integrated oil company, such as Texaco, is involved in all phases of the business, from the exploration for oil deposits to marketing the f i n a l products to the consumer. There are six principal fields of operation i n which the integrated oil company participates: Exploration, D r i l l i n g and Production, Transportation, Refining and Manufacturing, Petrochemicals, and Marketing. The petroleum industry is doing a marvelous job of coordinating these operations, employing a large scale, highly efficient logist i c a l network to deliver an abundant supply of products to consumers at relatively low prices. It i s estimated that we have now in the United States in proven o i l f i e l d s , reserves of o i l equal to or greater than the amounts that already have been produced. The problem i s that the o i l l e f t in many of the o i l fields i s not readily produced. It is entrapped in the geological formation, or "sand", by strong capillary forces which resist displacement by other f l u i d s . Enhanced o i l recovery methods are now at the forefront of research and development efforts of the major o i l companies and of many smaller organizations as well. Some of the older fields have been water-flooded to strip the sands of some of their residual o i l . Conventional water flooding, however, s t i l l leaves more than half of the original o i l i n place.

by systematic and aggressive patent programs. Patents p r o t e c t processes and products f o r a company's own use and, i n the case of products, o f t e n provide a competitive advantage i n the consumer market. You are made aware o f some of the patented products by a d v e r t i s i n g programs. You know, f o r example, that one brand o f motor o i l i s s a i d to g i v e the m o t o r i s t increased gasol i n e mileage because i t contains patented f r i c t i o n m o d i f i e r s . With another brand, engines are kept c l e a n e r and run longer because o f c e r t a i n patented a d d i t i v e s i n the l u b r i c a t i n g o i l s . Top brand g a s o l i n e s keep c a r b u r e t o r s and spark plugs c l e a n and prevent c a r b u r e t o r i c i n g and c o r r o s i o n by the use o f patented additives. The l i c e n s i n g of company owned patents and p r o p r i e t a r y know-how i s common everyday p r a c t i c e i n the petroleum i n d u s t r y . The g e n e r a l p o l i c y i s t o make technology a v a i l a b l e to q u a l i f i e d a p p l i c a n t s through l i c e n s i n g a t reasonable r o y a l t y r a t e s . Aside from a few exceptions, patented processes, compositions, and apparatus are a v a i l a b l e to others i n s i d e or o u t s i d e the i n d u s t r y . Some o l d e r and w e l l e s t a b l i s h e d processes are a v a i l a b l e f o r l i c e n s e a t standard r o y a l t y r a t e s . Process r o y a l t y r a t e s are commonly based on the q u a n t i t y processed, that i s , b a r r e l s o f feed stock s u p p l i e d to a c a t a l y t i c c r a c k i n g u n i t , o r the amount o f product, f o r example, pounds o f toluene produced. In the case o f chemicals o r c a t a l y s t s , the r o y a l t y may be based on pounds o f chemicals used or produced or on the net s a l e s p r i c e o f the product. Apparatus may be l i c e n s e d on a per u n i t b a s i s . Royalty r a t e s and other d e t a i l s o f l i c e n s e agreements a r e determined by n e g o t i a t i o n . The r o y a l t y r a t e o f t e n i s determined by the value o f the technology t o the l i c e n s e e . Since most companies are both l i c e n s o r s and l i c e n s e e s , the p r e v a i l i n g view i s t h a t the terms of a l i c e n s e agreement should be such t h a t i t i s a good business d e a l f o r both p a r t i e s . A survey by Business Week (1) i n d i c a t e s that the petroleum i n d u s t r y spent something over $750 m i l l i o n i n 1976 f o r r e s e a r c h and development.

T h i s need f o r investment c a p i t a l r e s u l t s i n a cutback i n s e r v i c e s , such as r e s e a r c h and development, and consequently, i n o b t a i n i n g p a t e n t s . As a r e s u l t , the number of patents i s s u e d to the f i v e most a c t i v e o i l companies decreased a t the r a t e of about s i x percent per year from 1974 t o 1977. A survey by C i t i b a n k (2) showed t h a t f o r the p e r i o d 1970 t o 1975 the c a p i t a l o u t l a y s o f 37 United States-based o i l companies exceeded t h e i r a v a i l a b l e cash flow. In 1975, f o r example, the cash flow s h o r t f a l l amounted t o more than 10 b i l l i o n d o l l a r s . Changing economic c o n d i t i o n s and the increased dependence o f the United States on f o r e i g n o i l have created a demand f o r enormous amounts o f c a p i t a l and f o r new r e f i n e r y p r o c e s s i n g equipment and petrochemicals p l a n t s .

c a p i t a l and e x p l o r a t o r y expenditures of Texaco {3) f o r the 12 months ended September 30, 1977, were f o r producing o p e r a t i o n s . About 35 percent went f o r manufacturing and petrochemicals p l a n t s , with the remaining 5 percent covering a l l other c a p i t a l expenditures. As a r e s u l t o f t h i s squeeze on c a p i t a l , there has been a s h i f t i n emphasis i n R&D programs i n the o i l i n d u s t r y over the past s e v e r a l years. Fundamental r e s e a r c h and even long-term a p p l i e d research are being phased out i n favor of product r e search and other near-term a p p l i e d r e s e a r c h , such as enhanced o i l recovery p r o j e c t s and environmental programs. T h i s s h i f t i n emphasis i n r e s e a r c h expenditures i s not l i m i t e d to the p e t r o leum i n d u s t r y , as i s brought out i n an a r t i c l e i n a recent Wall S t r e e t J o u r n a l (4). A consequence of the shortage of c a p i t a l has been i n c r e a s e d p a r t i c i p a t i o n i n i n d u s t r i a l R&D by the F e d e r a l Government. In the past few years i t has become a major source o f c a p i t a l i n the a l t e r n a t i v e energy f i e l d s , p a r t i c u l a r l y i n the area of c o a l utilization. In the n o t - t o o - d i s t a n t f u t u r e , i f not today, only the F e d e r a l Government may be able to f i n a n c e the l a r g e c o a l conversion p l a n t s needed to r e p l a c e o i l and n a t u r a l gas as industrial fuels. When a company accepts government f i n a n c i n g o f a development p r o j e c t , i t s patent and l i c e n s i n g program i n t h a t area w i l l have to be r e c o n c i l e d with government patent and data p o l i c i e s . In d e a l i n g with Government agencies, such as the Department of Energy (DOE) f o r f i n a n c i n g R&D, i t i s necessary to n e g o t i a t e the terms a f f e c t i n g the ownership o f patents and the c o n t r o l o f data and l i c e n s i n g r i g h t s . Dr. Betsy Ancker-Johnson, i n 1976, when she was A s s i s t a n t S e c r e t a r y f o r Science and Technology a t the Department of Commerce, i n commenting on the l a c k o f u n i f o r m i t y o f p o l i c y among the more than 20 government agencies funding R&D, estimated t h a t some 30,000 c o n t r a c t s per year must be n e g o t i a t e d with these agencies. Some o f these agencies a c q u i r e t i t l e to a l l i n v e n t i o n s , but may waive t i t l e to p r i v a t e s e c t o r c o n t r a c t o r s under c e r t a i n c o n d i t i o n s . Others acquire only a l i c e n s e to n a t i o n a l and s t a t e agencies, while s t i l l others permit a waiver of r i g h t s a f t e r an i n v e n t i o n i s made under the c o n t r a c t . As s t a t e d by Dr. AnckerJohnson, these n e g o t i a t i o n s have "placed an enormous and needless burden on both the agencies and t h e i r c o n t r a c t o r s " (5). Representative Ray Thornton (D-Ark.) on A p r i l 6, 1977, i n i n t r o d u c i n g a b i l l , H.R. 6249, to e s t a b l i s h a uniform patent p o l i c y (6) f o r i n v e n t i o n s r e s u l t i n g from f e d e r a l l y funded R&D, said: "Determining patent r i g h t s when an i n v e n t i o n i s the r e s u l t of f e d e r a l l y funded r e s e a r c h has become i n c r e a s i n g l y complex". Anyone who has been i n v o l v e d i n government c o n t r a c t s must c e r t a i n l y agree with t h a t .

Meanwhile we must l i v e with the patents and data clause requirements o f the v a r i o u s government agencies as they a r e today. When a company enters i n t o a c o n t r a c t w i t h DOE f o r the development o r l a r g e - s c a l e demonstration o f one o f i t s promising p r o p r i e t a r y processes, i t i s i n danger o f l o s i n g p r o p r i e t a r y r i g h t s i n both i t s i n v e n t i o n s and i t s data, o r know-how. Both patents and know-how are important l i c e n s i n g a s s e t s . Standard patent clauses i n DOE c o n t r a c t s p r o v i d e t h a t the t i t l e i n i n v e n t i o n s made " i n the course o f o r under the c o n t r a c t " i s i n the Government (9). Any i n v e n t i o n which i s f i r s t a c t u a l l y reduced to p r a c t i c e under the c o n t r a c t a l s o belongs t o the Government (10). T h i s means t h a t the Government may get t i t l e to i n v e n t i o n s made p r i o r t o the c o n t r a c t , but f i r s t a c t u a l l y b u i l t and used during the course o f work under the c o n t r a c t . Thus, the Government may a c t u a l l y o b t a i n t i t l e t o patents on i n v e n t i o n s made p r i o r t o the Government c o n t r a c t . The r e a l i n c e n t i v e i n e n t e r i n g i n t o an R&D c o n t r a c t i s t h a t the work under the c o n t r a c t w i l l l e a d t o commercial p l a n t s . For example, l e t ' s suppose you have developed a new process. I t looks good i n the l a b o r a t o r y , but before the process can be s o l d or used commercially, a demonstration p l a n t must be b u i l t . Your company i s unable t o r a i s e the money f o r the demonstration p l a n t , but the government agency i s both ready and w i l l i n g t o help w i t h f i n a n c i n g the p r o j e c t . Now, suppose t h a t d u r i n g the course o f the c o n t r a c t , the process i s f i r s t a c t u a l l y reduced t o p r a c t i c e . The government agency may get t i t l e t o a l l your i n v e n t i o n s , whether p r e v i o u s l y patented o r not, unless a waiver o f t i t l e was negotiated i n t o the c o n t r a c t . Now l e t us assume the process proves t o be a great success and i t looks as though 20 t o 30. f u l l s c a l e p l a n t s w i l l be b u i l t i n the United States and p o t e n t i a l l y t h a t many more abroad.

states and municipalities. So, you're l e f t i n a worse position than your competitors. You spent the seed money and they reap the harvest. There are some ways to get around this dilemma in negotiating contracts which are too involved to go into in this paper, except to say that you may negotiate, for example, to retain foreign licensing rights; you may r e s t r i c t release of data by limited rights provisions in the contract; and you may be able to assert a background patents position through requiring licensing under these patents at reasonable royalty rates (11). As you can see, the various factors mentioned are forcing reassessment of R&D and patent p o l i c i e s . F i r s t of a l l , i t i s important to try to identify promising inventions which were made prior to a government contract as inventions actually reduced to practice before work i s commenced under the contract. Patent applications covering these inventions should be already on f i l e before work begins under the contract. Close cooperation between the patent attorney and the research director should pinpoint those inventions which should be actually reduced to practice prior to a contract, then determine what acts are necessary to develop an actual reduction to practice of the important inventions with minimum R&D time and expense. The need for additional capital for R&D efforts in the private sector is abundantly apparent. It is hoped that Congress w i l l adopt a policy toward inventions resulting from Governmentsponsored R&D which w i l l permit industry to accept Government funding without fear of loss of i t s related proprietary technology as contained in patents and licensing rights. Abstract Competition in the petroleum industry necessitates large expenditures for research and development. Patents are essential to protect these investments. Active research i s carried out in the areas of exploration for petroleum deposits, data processing procedures, petroleum production techniques, offshore oil producing equipment, enhanced oil recovery methods, refinery and petrochemical processes, catalysis, new products, and improved fuels and lubricants. Extensive licensing of patents and know-how relating to improved hydrocarbon processing methods has been customary in the oil business for many years. Licensing royalties and terms usually involve lengthy bargaining. Licensing revenues are often plowed back into research resulting in continuing opportunities for employment of professional chemists and engineers. However, with government-financed contracts, r e s t r i c tive and regressive regulations pertaining to inventions, coupled with other requirements, such as environmental impact statements and increased taxation and equipment costs, have resulted in a decrease in private venture capital needed for research.
