T 2048/23 - Inherent or intrinsic properties

Key points

• The opposed patent contains in Table 1 the results of measurements of a certain parameter of  existing, commercially available, absorbent articles. The claim defines a range overlapping with the measured values.
• The Board: "Even if the parameter measurements on the articles seen in Table 1 were never performed publicly or at least were never made available before the priority date, these are intrinsic properties of the articles which are thus considered to have been made publicly available, see for example G 1/23, items 73, 90 and 91, or G 1/92, items 1.4, 2 and 2.1."
  • G 1/92: "There is no support in the EPC for the additional requirement (...) that the public should have particular reasons for analysing a product put on the market, in order to identify its composition or internal structure. ... The introduction of such an additional requirement would remove a commercially available and reproducible product from the public domain. "
  • Suppose the proprietor had invented a new measurement device that enables measurement of a (new) parameter that could not be measured using prior art measurement technologies. Suppose the claim specifies a range for the new parameter, and that the commercial prior art products (which were commercially available on the filing date) are found to exhibit a value of the parameter in the claimed range. Does it matter that the parameter was not analysable on the filing date?
