The Fire in the U.S. Patent Office

On the morning of September 24, a fire broke out in one of the attic model rooms of the Patent Office, in Washington, which destroyed part of the upper portions of the west and north wings of the buildings. It is not known how the fire originated, but spontaneous combustion among patented chemicals in the upper part of the building is assigned as a probable cause. The edifice above the third story was filed with patented documents and models, the latter made of light inflammable wood. The roof was also of wood. The fire, therefore, had abundant material whereon to feed, and made rapid headway.

It is gratifying, however, to know that all the lower portion of the building, which is fireproof, and in which the active affairs of the Patent Office are conducted, escaped permanent injury. None of the original patent documents were lost; all drawings, specifications, files, etc., remain intact, together with all caveats, assignments, and pending applications for patents. Consequently there will be no interruption of business.

The fire merely swept away a portion of the upper works of the edifice, and, perhaps not unfortunately, destroyed a great accumulation of rubbish. The re-roofing will be rapidly pushed forward, and it probably will be so carried out as to render the business facilities of the Office better than before the fire.

The Proposed Amendments to the Patent Laws

We give below an abstract of the new patent bill which has been introduced into the Senate by Mr. Wadleigh.

The first section enacts that from and after the passage of the act no profits or damages in any suit for infringement of a patent shall be recovered which shall have accrued more than four years preceding the commencement of each suit, and that all rights of action at present existing must be sued for within four years thereafter. Under this section, if there are a hundred infringers of a patent, a hundred suits must be brought at once to fully protect it; or if an eastern man has a patent, and someone in the extreme west wishes to manufacture the patented article, he may do so for many years before his operations are discovered, and the owner of the infringed patent has no right to recover any damages accruing to him from the infringement that occurred more than four years before suit is brought.

Under the second section a license fee is to be the measure of damages which a patentee may recover from infringers, provided any such license fee has been established; but if not, where from the nature of the invention it can be made to appear to be for the interest of the patentee that other persons should use the same, the court or jury shall determine the damages from the evidence, and in such case no account of profit or savings is to be allowed. Where profits are to be taken into consideration, the defendant is not to be charged with any saving he may have made by infringing a patent, unless it can be shown that he has made money by his business. Where he acknowledges that profits have accrued from his infringement, the court is to determine what proportion of the profit is due to the said invention and what to the other elements from which such profit was derived, and the proportion due to the invention is to be the measure of profit recovered; but if said profits shall be found to be in excess of the injury done by the infringement, the court is to diminish the amount to such an extent as may be just and reasonable. This last clause appears to be open to the interpretation that, if the defendant can prove that from the want or means or otherwise the patentee was in such a position as to be unable to use his invention, and was not therefore actually injured by the infringement, notwithstanding the infringer may have made an immense profit from the use of it, unless it can be shown that the inventor actually suffered great injury, he is to be cut down in the profits to the amount of injury he has suffered.

Section 6 has a clause to the effect that no machine or other article made prior to the surrender and reissue of a patent which did not infringe such surrendered patent, shall be held to be an infringement of the new claim of the reissued patent.

Section 9 allows infringers, where a patentee does not bring suit immediately he has knowledge of infringement, to bring a bill in equity to declare such infringed patent void for any of the causes which by law may render the same invalid. So that in case a patentee is too poor to immediately bring a suit against a wealthy infringer of his patent, said infringer may bring suit to declare it invalid; and in nine cases out of ten where the owners are too poor to employ good counsel to protect their rights, perfectly valid patents would be declared void under such circumstances.

Section 10 is to compel patentees to bring suits to enforce their rights, if an infringer demands that a suit be brought no matter whether the patentee have means to bring such suits or not, under the penalty of being enjoined from ever prosecuting such infringer at any time thereafter.

Section 11 is an imitation of the English law in the matter of fees, and it requires that a patentee shall pay fifty dollars on or before the first day of January after the expiration of four years from the date of the patent, and one hundred dollars on or before the first day of January next after the expiration of the ninth year of the patent. In default of either of these payments, the patent is to expire on the 1st day of April next thereafter, and during that month the Commissioner of Patents is to publish a list of the patents that have expired for the non-payment of these extortionate fees. In view of the fact that there is now in the Treasury of the United States over a million of dollars wrung from poor inventors in the shape of unnecessarily high patent fees, we think comment on this section entirely needless.
