Opinion:
PERRY, Senior District Judge.
After being accused of patent infringement, plaintiff-appellant Ortho Pharmaceutical Corporation [hereinafter "Ortho"] brought a declaratory judgment action against defendant-appellee American Hospital Supply Corporation [hereinafter "AHS"], as the exclusive licensee of claims 1 through 8 of United States Letters Patent 3,486,981 under an agreement with defendant-appellant Roy E. Speck, to whom the patent was issued on December 30,1969, for "Substances Relating to Testing of Blood-Coagulation." Under the agreement, AHS has the right to make, use and sell partial thromboplastin time test [hereinafter "PTT test"] reagents, which are substances used in blood-coagulation tests. In its complaint, filed March 3,1972, Ortho asked the United States District Court inter alia to adjudge that Speck's patent was invalid and that the manufacture, sale and use of Ortho's Activated Thrombofax Reagent [hereinafter "Thrombofax"] had not infringed it. Because Ortho had brought the action in New Jersey and had not joined Speck as a co-defendant, AHS moved on August 1, 1972, to dismiss or in the alternative to transfer the action to the Southern District of Indiana. Twenty-eight days later, Ortho amended its complaint to restrict the matter in suit to claims 1 through 8 of Speck's patent.
Ruling upon AHS's motion, District Judge Clarkson S. Fisher, — in a commendably thorough opinion order, — found that Speck was an indispensable party to the action and that a declaratory judgment action could not be defended by the licensee alone. Instead of dismissing the action, however, Judge Fisher ordered it transferred to the Southern District of Indiana. There, in order to comply with an order of District Judge Cale J. Holder that Speck be made a party defendant, Ortho further amended its complaint to name Speck as a co-defendant. In September, AHS and Speck answered the second amended complaint and Speck filed a counterclaim against Ortho for patent infringement. Or-tho answered the counterclaim the next month. Thereafter, extensive discovery was made by the litigants until February of 1975 when Ortho filed an amendment to its second amended complaint. In the amendment Ortho added an allegation that claims 1 through 8 are invalid under the provisions of both paragraph 1 and paragraph 2 of 35 U.S.C. § 112. The case was then tried. At the trial, Ortho's declaratory judgment complaint was dismissed without prejudice and the case was tried on the issues raised by the counterclaim.
On June 30, 1975, District Judge Holder entered unreported but very thorough Findings of Fact and Conclusions of Law. On July 18, 1975, Ortho filed a confidential motion to add evidence excluded during the trial as evidence for purposes of appeal. On July 29, 1975, Judge Holder entered a judgment in which he adjudged inter alia that claims 1, 2, 5, 6, 7 and 8 of Speck's patent are valid and that the counterdefendants, Ortho and Ortho Diagnostics, Inc. [hereinafter also "Ortho"] , had infringed said claims. The same day, Judge Holder issued a writ of injunction enjoining said counter-defendants from making, using or selling Thrombofax in the United States during the life of Speck's patent.
On August 8th, Ortho appealed the judgment of July 29, 1975 and Judge Holder stayed the enforcement of the judgment pending appeal. On September 11th, Judge Holder denied Ortho's motion of July 18th (to add evidence excluded during the trial).
Ortho exhorts us to reverse the decision of the District Court and to find that the claims in suit are invalid and have not been infringed by Ortho's Thrombofax. Ortho says that we should do so because in many critical areas the District Court's findings of fact are "unbelievably erroneous". We assume that within the meaning of Rule 52(a), 28 U.S.Code, Ortho is using the term "unbelievably erroneous" as a synonym for "clearly erroneous".
Ortho contends that the evidence clearly establishes that the claims in suit are invalid under the provisions of 35 U.S.C. § 103, 35 U.S.C. § 102(f) and (g), and 35 U.S.C. § 112. The contested claims are 1, 2, and 5 through 8. They are as follows:
1. A partial thromboplastin time test reagent comprising a platelet substitute, and ellagic acid as the chemical activator.
2. A partial thromboplastin time test reagent comprising a platelet substitute, and sodium ellagate as the chemical activator.
5. A partial thromboplastin time test reagent comprising a platelet substitute, and a monovalent salt of ellagic acid as the chemical activator.
6. A partial thromboplastin time test reagent comprising a platelet substitute, and an hydroxy-substituted aromatic compound as the chemical activator.
7. A partial thromboplastin time test reagent comprising a platelet substitute, and a salt of an hydroxy-substituted aromatic compound as the chemical activator.
8. A partial thromboplastin time test reagent comprising a platelet substitute, and a monovalent salt of an hydroxy-substituted aromatic compound as the chemical activator.
The claims in suit are invalid under 35 U.S.C. § 103, says Ortho, because what Speck did was obvious to a person with ordinary skill in the blood-coagulation field. They are invalid under 35 U.S.C. § 102(f) and (g), it is claimed, because Speck was not the first discoverer of the subject-matter of the claims in suit in that Dr. Ratnoff conceived and reduced to practice a PTT test reagént before Speck even conceived of his idea. They are invalid under 35 U.S.C. § 112, contends Ortho, because they do not distinctly claim an operative product in that none of claims 1, 2, or 5 contains any reference to ellagic acid or sodium ellagate prepared by any special method of the patent, and none of claims 6 through 8 contains any limitation with regard to any special method of preparing any of the broadly-claimed genus designated as "an hydroxy-substituted aromatic compound." Additionally, says Ortho, claims 6 through 8 are so broad that they encompass many inoperative chemical activators.
Validity of the Claims under 35 U.S.C. § 103
The District Court found that the subject matter of each of claims 1, 2, and 5 through 8 was not obvious to a person of ordinary skill in the blood coagulation field either in March of 1964 when Speck first prepared a PTT reagent by dissolving ellagic acid in sodium hydroxide, or on March 15, 1965, when Speck filed his patent application. We have reviewed the record carefully and we feel that it contains sufficient evidence to warrant this finding.
One difficulty we have with accepting Ortho's prior art argument is that Or- tho did not establish that Dr. Ratnoff's 1963 article, upon which Ortho depends for prior art, contained an enabling disclosure — a recital telling how to make and use the dilute solutions of ellagic acid in order to accelerate clotting. It is well settled that a publication must contain sufficient disclosure to enable a person of ordinary skill in the art to make and use the invention described in the patent before the patent will be invalidated by the prior art publication. See Seymour v. Osborn, 78 U.S. 516, 555, 20 L.Ed. 33, 42 (1870). The unsuccessful attempts of both Dr. Ratnoff and Ortho to prepare a PTT reagent containing ellagic acid in a true solution are further indications that Speck's claimed invention was not obvious even after Dr. Ratnoff's article was published. We agree with AHS that if Speck's invention was not obvious to a person of Dr. Ratnoff's eminent skill, it would not be obvious to a person of ordinary skill in the art.
Perhaps the most important weakness of Ortho's obviousness contention is that Speck made a startling discovery by doing what Dr. Huseby said was a stupid thing to do, — using sodium hydroxide to dissolve ellagic acid. By doing this, Speck discovered that ellagic acid, unlike any other material known to Dr. Huseby, will remain in solution at a pH of 7.5 if it is first dissolved in a base at a higher pH and the pH is then reduced to 7.5 by adding an acid. Both Dr. Colburn and Dr. Huseby agreed that if a material is insoluble at a certain pH but is soluble at a higher pH, and if the pH is raised to dissolve the material and then lowered, the material would precipitate out of solution. But this does not happen with ellagic acid. The PTT test must be performed within the physiological pH range of about 7.3 to 7.5. This was confirmed by Dr. Ratnoff, who testified that the clotting test will not work unless it is done somewhere between pH 7 and 8. Dr. Huseby testified that he would not have used sodium hydroxide to dissolve ellagic acid after reading the 1963 article of Dr. Ratnoff because of the pH at which the reagent had to function and because of the molecular structure of ellagic acid. Dr. Huseby went so far as to say that the idea of using sodium hydroxide to dissolve ellagic acid was "stupid" and that he was "horrified" to learn that Speck's licensee was dissolving ellagic acid in this manner until he learned that Speck's procedure actually worked. The trial judge had a right to credit Dr. Huseby's testimony, and Ortho's vigorous attack on Dr. Huseby's qualifications and on his testimony fails to persuade us that Dr. Huseby was not a credible witness and that the trial judge's findings based upon Dr. Huseby's testimony were clearly erroneous.
Secondary considerations, too, indicate that Speck's invention was not obvious. First, the commercial success of his invention is indicated by the fact that up to the date of the trial Speck received more than $75,000 in royalties. Ortho concedes that reagents prepared in accordance with Speck's patent can be more conveniently used by untrained help and with instruments. (Reply Brief for Appellants at 1). The reason for this is that such reagents permit the PTT clotting times to be determined automatically by optical instruments. Second, that there was a long-felt but unsolved need for a PTT reagent with a soluble activator is indicated by problems with non-activated PTT tests and particle-activated tests, by Ortho's search since 1961 for a workable soluble activator and its subsequent switch to Speck's procedure after it analyzed his licensee's reagent. Third, the failure of others is indicated by Dr. Ratnoff's failure to solve his suspension problems and by Ortho's failure to solve suspension and precipitation problems until after it began using sodium hydroxide.
Moreover, the usual presumption of validity under 35 U.S.C. § 282 is strengthened when the Patent Office specifically considered the prior art which is urged to invalidate the patent by an accused infringer. Shumaker v. Gem Mfg. Co., 311 F.2d 273, 275 (7th Cir. 1962); AMP, Inc. v. Vaco Products Co., 280 F.2d 518, 521 (7th Cir. 1960). Speck himself referred to Dr. Ratnoff's 1964 publication in column 4 of his patent and this publication was used as reference by the Patent Office and was listed among the references at the end of the patent. Dr. Ratnoff's 1963 article is an abstract of his 1964 publication. The 1963 article is therefore no more pertinent than the 1964 publication. Ortho relies on the Merck Index for the statement that ellagic acid is soluble in alkalies, but the Patent Office cited the Jurd reference for the statement that ellagic acid is soluble in sodium hydroxide. We feel that there is ample support for the trial judge's finding that none of the prior art relied on by Ortho is any more pertinent than the prior art which the Patent Office considered before granting the patent.
Validity of the Claims under 35 U.S.C. § 102(f) and (g)
We also cannot accept Ortho's contention that Dr. Ratnoff rather than Speck was the first discoverer of the subject matter of the claims in suit. Experiments by both Speck and Wilbourn established that Dr. Ratnoff had, not a true solution of dissolved ellagic acid, but merely a suspension of undissolved ellagic acid particles. The record as a whole supports the District Court's finding that any activation of the Hageman factor obtained by Dr. Ratnoff's reagent was caused by these undissolved particles of ellagic acid. In contrast to what Dr. Ratnoff did, Speck prepared a reagent in which the ellagic acid was in true solution.
Ortho also argues that regardless of whether the ellagic acid in Dr. Ratnoff's reagent was a true solution or only a suspension of undissolved particles, the ellagic acid nonetheless acted as a chemical activator as those words are used in the claims. The District Court found, however, that the words "chemical activator" as used in Speck's claims refer to- an activator in solution as distinguished from insoluble activators. We agree with the appellees that the meaning of these words must be determined with reference to the specification as a whole when read by a person skilled in the art to which the patent pertains, the reason being that the specification of the patent is addressed to such persons. See Carnegie Steel Co. v. Cambria Iron Co., 185 U.S. 403, 407, 22 S.Ct. 698, 700, 46 L.Ed. 968, 971 (1902). We think that Dr. Murray's testimony amply supports this finding of the District Court.
Validity of the Claims under 35 U.S.C. § 112
Nor can we accept Ortho's contention that the claims in suit are invalid under 35 U.S.C. § 112. Ortho's argument that claims 1, 2, and 5 do not cover any operative product is countered by Speck's testimony, when taken as a whole, and by that of Dr. Murray.
Ortho argues that claims 6 through 8 are so broad that they embrace many inoperative chemical activators, but Ortho has failed to prove that any hydroxy-substituted aromatic compounds would be inoperative in a PTT reagent prepared in accordance with Speck's patent. Further, we are persuaded that Speck is not claiming hydroxy-substituted aromatic compounds per se, but is claiming a PTT reagent which includes only those hydroxy-substituted aromatic compounds which function as a chemical activator of the Hageman factor. See Application of Fuetterer, 319 F.2d 259 (C.C. P.A.1963), where the Patent Office rejected a claim which included "an inorganic salt" as an ingredient on the ground that not all such salts could perform the function described in the claim. The court reversed, stating that the applicant had described and claimed his invention as comprehending the use of inorganic salts which were capable of performing a specific function and that the claims would be limited accordingly. Finally in this connection, this court has said that the claims of a patentee should be interpreted liberally so as to uphold and not destroy his right in the substance of his invention. Reese v. Elkhart Welding and Boiler Works, Inc., 447 F.2d 517, 525 (7th Cir. 1971).
Infringement
Ortho finally contends that the District Court erred in finding that all the claims in suit were infringed by Ortho. The testimony of Wilbourn, Speck and Dr. Huseby, pertinent responses to requests for admission, evidence of Ortho's manufacturing procedures and reagents prepared by Speck in accordance therewith, supply sufficient support for the court's finding of infringement.
Ortho's Confidential Motion
The District Court did not err in denying Ortho's confidential motion to add evidence excluded during the trial. Ortho contends that the excluded evidence would have damaged Dr. Huseby's credibility, but it is well settled that even newly-discovered evidence — which is not the case here — generally cannot be the basis for a new trial when such evidence is strictly impeaching in nature. See Wroblewski v. Exchange Insurance Assn, of Chicago, 273 F.2d 158, 162 (7th Cir. 1959).
For all of the foregoing reasons, the judgment of the District Court is Affirmed.
. Ortho Diagnostics, Inc., a plaintiff-appellant herein, is the successor to plaintiff-appellant Ortho Pharmaceutical Corporation. It is not clear from the record when plaintiff-appellant Ortho Diagnostics, Inc., became joined as a party. The first record document on which it appears as a party is the Findings of Fact and Conclusions of Law entered on June 30, 1975 by Judge Holder.
. 35 U.S.C. § 103 provides:
§ 103. Conditions for patentability; non-obvious subject matter.
A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. (July 19, 1952, ch. 950, 66 Stat. 798.)
35 U.S.C. § 102(f) and (g) provides:
§ 102. Conditions for patentability; novelty and loss of right to patent.
A person shall be entitled to a patent unless—
(f) he did not himself invent the subject matter sought to be patented, or
(g) before the applicant's invention thereof the invention was made in this country by another who had not abandoned, suppressed, or concealed it. In determining priority of invention there shall be considered not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, from a time prior to conception by the other. (July 19, 1952, ch. 950, 66 Stat. 797.)
35 U.S.C. § 112 provides:
§ 112. Specification.
The specification shall contaih a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. A claim may be written in independent or dependent form, and if in dependent form, it shall be construed to include all the limitations of the claim incorporated by reference into the dependent claim.
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. (July 19, 1952, ch. 950, 66 Stat. 798; July 24, 1965, Pub.L. 89-83, § 9, 79 Stat. 261.)
