The -question involved in.this case is whether the *15bill in the patent ease complies with equity rule No. 25. The purpose of these rules was to define the issue the plaintiff was to try, and so advise the defendant as to enable him to prepare to meet such issue. This was to be done, as stated in the rule, by “a short and simple statement of the ultimate facts upon which the plaintiff asks relief, omitting any mere statements of evidence.” On demurrer, the court below held the bill did not comply with the rule, and dismissed the bill. Thereupon this appeal was taken.
Now, as the ultimate facts upon which the plaintiff asks relief were, first, grant of a patent; second, ownership thereof by the plaintiff; third, infringement thereof by defendant — the question here involved is the plaintiff's bill, a short and simple statement of these ultimate facts which omits statements of evidence. We select one patent as typical, which the bill thus states:
“Max E. Moeller, being the first, original, and sole inventor of certain new and useful improvements in hydrometer, and being then as such inventor the person entitled by law to apply for and receive letters patent of the United States therefor, did in due form and apt time, and in full compliance with the statutes in such eases made and provided, on, to wit, May 26, 1915, file his application with the proper department of the government of the United States for the grant to him of United States letters patent upon and for the aforesaid invention.
“Thereupon such proceedings were had upon and pursuant to said application, and in due form and in full compliance of all the requirements of law then in force, that on, to wit, March 28, 1916, United States letters patent No. 1,177,128 were lawfully granted to said Max E. Moeller for said invention, which letters patent are now in full force and effect, and which letters patent, or a duly certified copy thereof, are ready in court to be produced as and when this honorable court may direct, and a eopy of which letters patent is attached hereto as Exhibit A and made a part hereof.”
The court below held that:
“The said bill of complaint is defective, in that it fails to set forth that the inventions at issue were not in public use nor on sale ■ in this country for two years before the application for letters patent thereon.
“The said bill of complaint is defective, in that it fails to allege that the inventions at issue were not patented nor described in a printed publication in this or any foreign country for two years before the application for letters patent thereon.”
We shall not discuss the case pro and eon on this question, but confine ourselves to stating why we hold the averments of the bill eomply with the rule. The first issue sought to be raised by the bill was the grant of a patent. Can there be any question that such issue was sufficiently averred? It was averred the patentee was “the first, original, and sole inventor”; theft as such inventor he was “entitled by law to apply for and receive letters patent of the United States therefor”; that “in full compliance with the statutes in such ease made and provided,” he did on May 26,1916, apply therefor; that on “March 28, 1916, United States letters patent No. 1,177;128 were lawfully granted” to him. In addition to these averments the bill made profert of the original letters patent or a certified copy thereof in these words: “Which letters patent, or a duly certified eopy thereof, are ready in court to be produced as and when this honorable court may direct, and a copy of which letters patent is attached thereto as Exhibit A, and made a part hereof.”
What more could be required in averment by demurrer, or in proof at trial ? By familiar principles of pleading, profert made the letters themselves part of the pleadings. If the letters patent themselves, or a certified eopy thereof, were offered and received in evidence, would they not establish the due grant of the patent? Occasionally a file wrapper is put in evidence, for the purpose of showing some procedural step, but in the trial of cases the usual course of court and counsel has been to treat the sheet office copy of specifications, drawings, and claims as evidencing the grant of a patent, without resorting to even the letters patent themselves, or a certified copy thereof. If the letters were offered in evidence, would an objection avail that it should not be received in evidence until the plaintiff had first proved, or offered to accompany by proof, that the invention had not been in public use or on sale in this country for two years, or was not patented or described abroad in a printed publication for two years before application. These are the negative requirements of the statute as to an inventive right to a patent; they are not requirements as to a patentee’s prima facie right of action on a patent granted.
Assuredly such use, sale, or publication was an affirmative fact, to be proved, by a defendant, and not one the plaintiff was called on to negative. His letters patent issued by the government was the ultimate fact on which, as the rule states, “the plaintiff asks *16relief,” and in no sense could this defense matter, which the defendant had to prove, be aptly described as “an ultimate fact upon which the plaintiff asks relief.” So, also, with regard to the assignment and consequent ownership of the patent. The bill avers that subsequent to the grant of said letters patent No. 1,177,128, “by an assignment in writing duly executed and recorded,” and proferí of which original assignment, or a duly certified copy thereof, plaintiff was vested with “all the right, title, and interest in, to and under said letters patent No. 1,177,128.”
On demurrer, therefore, the court had by these averments and proferís the ultimate facts of patent issue and patent ownership, which affirmatively and sufficiently would, in the absence of countervailing proof, show the plaintiff’s right to recover infringed. And the averments of the bill specified and thus advised the defendant wherein infringement was alleged. The patent was for a hydrometer, and the bill specified two types of hydrometer, which the defendant made and sold in the city of Scranton by the name of “Simplex,” “Kant Stick,” and “Sturdy,” as embodying and infringing certain specified and numbered claims. If these averred facts, patent issue, patent ownership, and patent infringement were proved as averred, and the defendant gave no countervailing defense, undoubtedly the plaintiff pleaded á sufficient case, and was entitled to recover, and in our judgment so construing and applying the rule in question is a step in furthering simplicity of statement, definition of issue, and information to the defendant.
The decree below will therefore be reversed, and the cause remanded, with instructions to reinstate the bill and proceed in due course.
