PARTICULARS OF OBJECTIONS.

In the High Court of Justice,

Chancery Division.

Between Albert Jones, Plaintiff,

and

William Dickson, Defendant.

Take notice, that the defendant will, on the trial of this cause, rely on the following objections to the validity of the letters patent sued upon:

(1) The said Albert Jones was not the true and first inventor of the alleged invention. The true and first inventor thereof was Richard Roe of 36 Oxford St., London.

(2) The said alleged invention was not new at the date of the said letters patent. It had been published:

(a) By the public manufacture, sale and use of drilling machines constructed in accordance with the said invention from the year 1899 to the present day at Huddersfield by the defendant, and also by James E. Smith, of Bolton, Lanes. Machines so manufactured are now in existence and may be inspected by the plaintiff at 17 Oxford Street, London. (b) By the public manufacture, sale and use of machines constructed in accordance with the said invention from the year 1902 to the year 1905 at Lincoln by William Thompson, of Lincoln. The said articles are no longer in existence. A description and drawings of the said articles are delivered with these particulars.

(c) By the public manufacture, sale and use of machines by means of the patented process at Bolton by John Thomas of Bolton, from the year 1896 until the year 1898. A description of the said process of William Harris, of Bolton. The defendant will endeavor to obtain inspection of the apparatus by the plaintiff.

(d) By the deposit in the Patent Office Library of the following specification of letters patent granted in foreign countries:

[blocks in formation]

(f) By the deposit in the Library of the British Museums in the year 1897 of a work bearing the title "DRILLS AND DRILLING MACHINERY" by William E. Vassas, and in particular by the passage commencing at p. 76, line 7 and ending at p. 80, 1.14.

(3) The said alleged invention was not proper subject-matter for letters patent having regard to the common general knowledge at the date thereof. The defendant will rely upon the specifications set forth under paragraph 2 hereof as part of the common general knowledge of the art.

(4) The said alleged invention was not useful.

(5) The specification is insufficient to enable the invention properly to be carried into effect. The plaintiffs will rely upon the passage of p. 2, 1.14 to p. 3, 1.3, wherein no sufficient directions are given for causing the cam J to effect the required movement.

(6) The specification gives directions which are misleading and dangerous. If the directions on p. 3, 1.12 to p. 3, 1.24, are carried out, the machines will not work.

(7) The subject-matter of the said letters patent was the subjectmatter of a prior grant of letters patent to William Davis dated January 2d, 1907, and numbered 368 of 1907, which letters patent were and are good and valid.
