Claim Rejections - 35 USC § 103
The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action:
(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 13-14, 16-18, 21, 23 are is/are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Thiers (WO01/96688) in view of Boucke (WO2006/058548).
Per claim 13, Thiers figures 7-8, as modified shows the panel comprises a substrate of a material on the basis of synthetic material; wherein the panel comprises a top layer above said substrate; the top layer having a planar surface, wherein this panel is rectangular, either oblong or square, and thus comprises a first pair of opposite edges and a second pair of opposite edges; wherein both pairs of opposite edges comprise coupling parts allowing to couple a plurality of such panels to each other; wherein these coupling parts, at the first and second pairs of edges, form a first locking system effecting a locking in the plane of the panels and perpendicular to the respective edges, and form a second locking system effecting a locking transverse to the plane of the panels; wherein these coupling parts, at first and second pairs of edges, substantially are realized from said substrate; wherein these coupling parts, at least at one of the aforementioned first and second pairs of edges, comprise a tongue and a groove, as well as a locking part at the tongue and a locking part at the groove, which, in a coupled condition of two such panels, prevent the drifting apart of the tongue and groove via contacting locking surfaces; wherein said groove is bordered by a lower lip and an upper lip, wherein the lower lip extends laterally up to beyond the distal end of the upper lip; wherein said locking part at the groove is located at said lower lip; wherein the locking part at the groove has an uppermost point defining a horizontal level, and wherein the horizontal level intersects the groove at a location that is situated proximally from a most distally situated point of said contacting portion at the underside of the upper lip, wherein the tongue and groove are arranged such that, when first and second panels having a structure of said panel for forming said floor covering, at respective edges, are presented to each other in a plane parallel manner in an uncoupled condition of the first and second panels (figure 8), such that the plane parallel manner is defined as the planar surface of the first panel being parallel to the planar surface of the second panel, and the planar surface of the first panel being lower than the planar surface of the second panel, the tongue of the second panel, at least with a tip of the tongue, is configured to already sit at least partially underneath the lip bordering the upper side of the groove of the first panel, without any bending being necessary (figures 5-8).
Thiers does not show wherein a smallest thickness of a portion(the protruded surface/area next to the groove) of the lower lip situated beyond the distal end of the upper lip and proximally of the locking part at the groove (figure 7), is at least 0.7 times an average thickness of the upper lip measured at a location of a contacting portion at the underside of the upper lip, which, in coupled condition of two of such panels, cooperates and forms direct contact with the upper side of the tongue at the respective opposite edge; the contacting portion defines a contact area distinct from remaining portions of the underside of the upper lip,.
Boucke figure 1, shows a smallest thickness of a portion(figure 2, the thinnest groove portion above 2a) of the lower lip situated beyond the distal end of the upper lip and proximally of the locking part at the groove, is at least 0.7 times an average thickness of the upper lip measured at a location of a contacting portion at the underside of the upper lip(figure 1 shows the claimed ratio), which, in coupled condition of two of such panels, cooperates and forms direct contact with the upper side of the tongue at the respective opposite edge; the contacting portion defines a contact area distinct from remaining portions of the underside of the upper lip.
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Thiers to show a smallest thickness of a portion(figure 2, the thinnest groove portion above 2a) of the lower lip situated beyond the distal end of the upper lip and proximally of the locking part at the groove, is at least 0.7 times an average thickness of the upper lip measured at a location of a contacting portion at the underside of the upper lip(figure 1 shows the claimed ratio), which, in coupled condition of two of such panels, cooperates and forms direct contact with the upper side of the tongue at the respective opposite edge; the contacting portion defines a contact area distinct from remaining portions of the underside of the upper lip as taught by Boucke with a reasonable expectation of success in order to form tongue and groove locking are that is strong against vertical load as the thicker thickness would enable the panel to better resist against vertical load per stronger tongue thickness.

Response to Arguments
Applicant's arguments filed 1/29/2026 have been fully considered but they are not persuasive.
With respect to claim 1, Boucke figure 1 shows downward inclination from the localized contacting portion in a proximal direction. Thiers as modified by Boucke, shows the localized contact portion being distinct from remaining portions of the underside of the upper lip, and the contacting portion forming a downward inclination in a proximal direction arranged at an inclined angle relative to the plane of the panel. Thiers also shows the claimed contact portion (the part that contacts the upper part of part 8). Thiers’ localized contacting portion in figure 5, shows contacting area similar to applicant’s contact portion (55). Thiers shows spacings on either side of the localized contacting area similar to applicant’s contacting portion(55).
With respect to claim 13, Thiers as modified by Boucke shows the
“ smallest thickness…at least 0.7 times …” as claimed. The combination results in the tongue being stronger and thus results in an enhanced panel assembly.
With respect to claims 8-12, JP figure 4 shows spaces above and below the tip of the tongue. Thiers as modified thus shows the claimed spaces. The limitations to “ localized contacting portion…” are disclosed by Thiers. The combination thus shows the claimed limitations, and the motivation to combine is reasonable as set forth above. With respect to “ contacting portion…structurally distinct…”, the reference Thiers shows claimed limitation as the contacting area is similar to the applicant’s area (55).
