AMENDMENT OF APPLICATIONS.

1. VALIDITY-REQUIREMENTS OF THE OFFICE.-The rule is that insertions by way of amendment in the description or drawing, or both, of a patent application do not invalidate the patent if they are only in amplification and explanation of what was already reasonably indicated to be within the invention, and this rule applies with special force where the insertion was required by the Patent Office. d General Electric Co. v. Cooper Hewitt Electric Co., 261.

2. APPLICATION-NEW MATTER.-Where plaintiff's original application disclosed as the preferred form of the invention the combination of a variable-speed engine, a generator driven therefrom through a magnetic clutch adapted to be rendered intermittently operative, a storage battery to be charged by the generator, and a relay in series in the charging-circuit arranged to intermittently energize and deënergize the clutch to hold the charging-current as nearly constant as possible, and where Figure 5 disclosed a continuously-driven generator provided with a rheostatic generator-field regulator adapted to be gradually operated in one direction or the other through relaycontrolled magnetic clutches of the same type as used in the preferred form and the purpose of the arrangement of Fig. 5 was also to maintain constant" a function of the output, and where the invention resided in the combination, the broad idea of regulating the current in such a system being old, and where there was no word of warning that a particular type of relay was essential, Held that amendments are invalid which substitute a pulsating-current theory of operation based upon the action of a particular type of relay, which mode of operation was not originally mentioned and was impossible with Fig. 5, which was accordingly canceled. H. Ward Leonard, Inc., v. Maxwell Motor Sales Corporation, 317.

3. Same—SamE.—The practice of amending a case by insertion of nebulous claims and cryptic allusions to possible alternative forms, with the purpose of anticipating subsequent developments in the art, where more explicit amendments would have caused the Examiner to raise the question of new matter, condemned. Id.

4. SAME

SAME.-Where certain elements are selected for the combination in an application as orginally filed, applicant cannot abandon elements originally selected as necessary and substitute other elements not originally suggested as essential where a wholly new idea of cooperation results. Id.

ANTICIPATION-Continued.

1. PATENTS-PUBLICATION.-An inventor's own publication of the device for which he seeks a patent more than two years prior to the applition is a disclosure within Revised Statutes, section 4886, (Comp. St., 1916, sec. 9430,) and precludes the patenting of his invention. d Wagner v. Meccano Limited, 231.

2. RULE 75 CONSTRUED AND APPLIED ANTICIPATION AND PRIOR INVENTION DISTINGUISHED.-A patent which discloses an invention in controversy and was granted after the filing of an application therefor, (or other reduction to practice,) on an application filed earlier, does not establish anticipation of that invention. The bar which it establishes, if any, is that of prior invention, as of the date of filing the application on which it was granted. Ex parte Thomas, 11.

APPEAL. See Construction of Trade-Mark Statutes, 2; Interferences, 8, 9, 10, 11; Patentability, 1; Priority of Invention, 7.

APPEAL TO THE COURT OF APPEALS OF THE DISTRICT OF COLUMBIA. See Jurisdiction of the Court of Appeals of the District of Columbia; Mandamus, 2.

RIGHT TO MAKE THE CLAIMS OF A DISSOLVED INTERFERENCE IN AN EARLIER APPLICATION.-Where the court dismissed C's appeal from a decision of the Commissioner of Patents dissolving an interference and denying C's motion to amend on the ground that the invention was not disclosed in an earlier application of C relied upon to carry his date back of a reference cited against the application which was involved in the interference, Held that C is not entitled to have the question reviewed on an ex parte appeal from a decision in that earlier application, denying his right to make the claims therein. *In re Creveling, 145.

APPEAL TO THE EXAMINERS-IN-CHIEF. See Cancelation of Claims, 1. APPEAL TO THE SUPREME COURT OF THE UNITED STATES. SUIT FOR INFRINGEMENT OF TRADE-MARKS-APPEAL AND CERTIORARI.—An appeal to the Supreme Court in a suit to restrain infringement of a trade-mark, allowed by one of the judges of the circuit court of appeals, dismissed under section 128, Judicial Code, as amended by act of January 28, 1915, (38 Stat., 803, ch. 22, sec. 2;) but, pursuant to stipulation, the transcript of the record filed for the purposes of appeal treated as a return to a writ of certiorari allowed by the Supreme Court. ** United Drug Company v.

CANCELATION OF CLAIMS.

1. APPEAL-REQUIREMENT.— -The recourse from a requirement of cancelation of claims, on the ground that they are to a different invention from that originally presented, is by appeal to the Examiners-in-Chief, not by petition. Ex parte Pearson, 36.

2. REQUIREMENT-REFERABLE TO LAW EXAMINER-RULE 42.-The basis of the requirement of cancelation of claims, on the ground that they are to a different invention from that originally prosecuted, is the same as that of the requirement of division-viz., that the inventions are independent or are of such a nature that they may not be joined in one application. Both requirements should be referred to the Law Examiner for approval, under Rule 42. Id.

CANCELATION OF TRADE-MARK REGISTRATIONS.

See Construction of

Trade-Mark Statutes, 3; Foreign Registrant; Registration of Trade-
Marks, 6.

1. ADVERSE DECISION IN INTERFERENCE.-Record reviewed and Held that in view of a trade-mark interference decision adverse to the registrant, G., it was proper, on motion of B., to cancel G.'s mark. * Great Bear Spring Company v. Bear Lithia Springs Company, 203.

2. INTERFERENCE. The law of February 20, 1905, applies to all registrations, and a registration under the law of 1881 may be canceled as an incident to an interference decision. Hudnut v. Phillips v. Mack, 74. 3. SAME ON DECISION ADVERSE TO A REGISTRANT INTERFERANT HIS REGISTRATION MAY BE CANCELED.-An interference between an applicant and a registrant necessarily involves both the question of right to register and the question of right to remain on the register, or validity of the existing registration, for it is necessary to remove an interfering registration from the register in order to make apparent and effective the award of right of registration to the applicant, and where the final decision in a trade-mark interference necessitates a holding that a registrant was not entitled to his registration and the prevailing interferant in effect moves for cancelation, Held that an order of cancelation will be forthwith entered.

1. INTERPRETATION OF SPECIFIC.-When dealing with an improvement in a well-developed art and it is established that one party is the prior inventor of the broad subject-matter of that improvement, the more specific counts should be interpreted in the light of the general disclosure. Count 3 awarded to Burt. * Burt v. Coats and Cameron. Coats and Cameron v. Burt, 131.

2. PATENTABILITY-DISCLOSURE OF APPLICATION.-Record reviewed and Held that the appealed claims cannot be predicated upon the disclosure of this application without forcing upon them a meaning which robs them of their sense. Ex parte Creveling, 5.

CLAIMS-Continued.

3. DIVISION-CARBON PILE.-Held that carbon piles have attained a distinct status in the art as subjects of invention independently of the systems in which they are to be used. Id.

4. ELECTION-RHEOSTAT AND SYSTEM.-Where C. elected to claim a system of which the carbon rheostat is an element, Held that he is estopped from afterward claiming the rheostat per se in that application. *In re Creveling, 145.

5. FORCE OF LIMITATIONS.-If a claim to the invention in controversy includes limitations which are not embraced in the tangible subjectmatter upon which the claims in such a patent are based and if those limitations state material and substantial parts of that invention, the patent does not establish the bar of prior invention, even though the difference did not require invention; but if the limitations merely state the operative environment of the invention in controversy then they do not state "material and substanial" parts of that invention and the patent does establish the bar. Ex parte Thomas, 11.

6. ALTERNATIVE.-Where claims 1 and 2 are for combinations in the usual form and claim 3 is for "the combination above set forth," plus certain additional matter, Held that this imports into claim 3 an alternative meaning depending on whether the additional matter is to be combined with the features of claim 1 or claim 2. Ex parte Holst and Leers, 44.

7. SAME.-Held that a subsequent claim can only refer back to a single combination for additional matter, in accordance with the longestablished practice against allowing alternative claims. (Ex parte Hulbert, C. D., 1893, 74; 63 O. G., 1687.) Id.

8. PRACTICE IN EX PARTE BROWN NOT EXTENDED.-Held that the practice outlined in ex parte Brown (C. D., 1917, 22; 235 O. G., 1355) is not extended beyond what was indicated therein. Id.

9. REJECTION.-Where the inventor's disclosure was fully contained in his
original specification, his claims thereunder having been rejected, a
substituted claim should not be read as purporting to cover with-
drawn suggestions of variant structures, so as to invalidate the same,
it appearing that the suggestions were withdrawn where the rejec-
tion of claims that were appropriate was acquiesced in.-a Rudd Mfg.
Co. v. Long-Landreth-Schneider Co. et al., 295.
10. MEANING CLEAR CONSIDERATION OF THE PRIOR ART NECESSARY.-
Where the Examiners-in-Chief in their decision said: "If their
meaning is clear and includes Jepson, no consideration of the prior
art need be given; if, however, there is no point to the claims when
read on Jepson, we do not understand that we are concluded from
a consideration of the prior art." Held that as they found, in effect,
that according to the normal meanings of the words used the claims
read on the applications of both parties it cannot be correctly said
that they erred in not considering the prior art. *Creveling v.
Jepson, 209.

COMMERCIAL SUCCESS. See Invention, 5; Particular Patents, 8. EXTENSIVE SALE OF THE MECHANISM.-Where the assemblage of the old elements and their operation in the manner indicated may save time and the mechanism may meet with a readier sale than other similar devices, Held that these things may result from mechanical skill and commercial enterprise and do not necessarily involve invention. **Grinnell Washing Machine Company v. E. E. Johnson Company, 363. COMMISSIONED OFFICERS. See Practice Before the Patent Office, 1, 2. COMMISSIONER OF PATENTS.

1. PRIORITY-UNIFORM DECISIONS.-In order to secure a reversal of the uni

form decisions of the Patent Office tribunals, Held that appellants must make out a very clear case of error. *Jobski and Griswold, Special Administrators of Bryant, deceased, v. Johnson, 140.

2. INTERFERENCE-MANIFEST ERROR.-"The three tribunals of the Patent Office, all experts, concur in awarding priority to Jepson. Where this is so, especially in a case of this character, we have repeatedly held that we will not disturb the decision of the Patent Office unless manifest error has been committed.' (Lindmark v. Hodgkinson, C. D., 1908, 540; 137 O. G., 228; 31 App. D. C., 612; Murphy v. Meissner, C. D., 1905, 592; 114 O. G., 1830; 24 App. D. C., 260; Stone v. Pupin, C. D., 1902, 550; 100 O.
