“Accordingly, the present invention provides spray apparatus comprising a pipe-work system that combines the feed and circulation lines on the spray boom to make a common feed when the machine is spraying and which converts back to recirculation when the sprayer is agitating, i.e. in a non-spraying condition. This also permits a reduction in the number of valves on the spray machine and greatly simplifies the pipe-work.”
“Thus the present invention permits:- 1. The use of the return line to provide extra flow to the boom when spraying. 2. A reduction in the size of the feed lines because the return line provides extra flow when spraying. 3. The purging of the spray line under pressure when filling with chemical. 4. The use of a single control valve to control the feed and return flows. 5. The ability to clean the system by incorporating clean water into the filling point (on board tank or independent supply).”
“Spray apparatus (1) of the kind having a liquid feed line (8b) connecting a supply of spray liquid (2) and at least one spray nozzle (9), a return line (8c) from the spray nozzle to the supply and a pump (3) for moving spray liquid from the supply (2) to the at least one spray nozzle (9) and for returning spray liquid from the at least one spray nozzle (9) to the supply (2) when the liquid is not being sprayed, characterised in that the liquid return line (8c) serves as at least a portion of the feed line when spraying.”
“(1) Applications for the protection of inventions in any of the Contracting States may be filed as international applications under this Treaty. (2) An international application shall contain, as specified in this Treaty and the Regulations, a request, a description, one or more claims, one or more drawings (where required), and an abstract. (3) The abstract merely serves the purpose of technical information and cannot be taken into account for any other purpose, particularly not for the purpose of interpreting the scope of the protection sought. (4) The international application shall (i) be in a prescribed language; (ii) comply with the prescribed physical requirements; (iii) comply with the prescribed requirement of unity of invention; (iv) be subject to the payment of the prescribed fees.”
“The Description shall disclose the invention in a manner sufficiently clear and complete for the invention to be carried out by a person skilled in the art.”
“The claim or claims shall define the matter for which protection is sought. Claims shall be clear and concise. They shall be fully supported by the description.”
“(1) The receiving Office shall accord as the international filing date the date of receipt of the international application, provided that that Office has found that, at the time of receipt: (i) the applicant does not obviously lack, for reasons of residence or nationality, the right to file an international application with the receiving Office, (ii) the international application is in the prescribed language, (iii) the international application contains at least the following elements: (a) an indication that it is intended as an international application, (b) the designation of at least one Contracting State, (c) the name of the applicant, as prescribed, (d) a part which on the face of it appears to be a description, (e) a part which on the face of it appears to be a claim or claims. (2)(a) If the receiving Office finds that the international application did not, at the time of receipt, fulfil the requirements listed in paragraph (1), it shall, as provided in the Regulations, invite the applicant to file the required correction. (b) If the applicant complies with the invitation, as provided in the Regulations, the receiving Office shall accord as the international filing date the date of receipt of the required correction.”
“(a) The request shall contain a list indicating: (i) the total number of sheets constituting the international application and the number of the sheets of each element of the international application: request, description (separately indicating the number of sheets of any sequence listing part of the description), claims, drawings, abstract; (ii) where applicable, that the international application as filed is accompanied by a power of attorney (i.e. a document appointing an agent or a common representative), a copy of a general power of attorney, a priority document, a sequence listing in electronic form, a document relating to the payment of fees, or any other document (to be specified in the check list); (iii) the number of that figure of the drawings which the applicant suggests should accompany the abstract when the abstract is published; in exceptional cases, the applicant may suggest more than one figure. (b) The list shall be completed by the applicant, failing which the receiving Office shall make the necessary indications, except that the number referred to in paragraph (a)(iii) shall not be indicated by the receiving Office.”
“The international application is checked by the receiving Office to determine whether it meets the requirements prescribed by the PCT as to the language, form and contents of international applications (the checks performed by the receiving Office are of a formal nature and do not go into the substance of the invention);”
“21. This is consistent with the provisions of Art.11(1). The receiving Office, which in many cases will act as little more than a staging–post before the application is forwarded to WIPO and an examining body, has to ensure that certain minimal formal requirements have been complied with. These formal requirements include those set out in Art.11(1)(iii). It is not required to test to see whether there is a description which meets the functional requirements of Art.5 PCT, merely that there has been filed an application which contains a part “which on the face of it appears to be a description”
“shall contain, as specified in this Treaty and Regulations, a request, a description, one or more claims, one or more drawings (where required), and an abstract.”
“9. Mr Davis acknowledged in the main that the check should go to form and not substance, although he did run an alternative argument based on the substance of the abstract that was included. I will come back to that later. But he was able to make some serious points concerning the form of the “numbered list”
“15. Mr Davis argued in the alternative that the text labelled Abstract had the correct structure for a claim and should be admitted as such. I cannot accept this because the text on that page is identified as Abstract, and as I said in Penife a body of text cannot be expected to serve two functions when convenient. It is a simple matter of labelling. Such analysis also requires something of an appreciation of the substance of the Abstract, which might be more than the checker should do. 16. Mr Davis also raised a human rights point concerning the deprivation of property that possible loss of this international application might involve. I appreciate that the penalty for an oversight in omitting claims is severe under the provisions of the PCT, but I and the UK Patent Office are bound in this matter by the clear terms of the PCT, which is an international obligation. I also have some doubts that the failure to launch an application in the first place should be regarded as a deprivation of property under Article 1 to the First Protocol to the European Convention on Human Rights. ”
