Abstract
A user-friendly golf swing practice mat is provided, comprising: (a) a low friction, compliant and resilient top sheet having a rigidity of less than 40 pounds per square inch; and (b) a bottom pad (natural grass or an accompanying compliant, resilient pad) for supporting the top sheet a finite distance above the underlying base, for providing space for the top sheet to yield to and accommodate the bottom-most portion of a reasonably well-aligned golf club swing-arc. The golf swing practice mat avoids the mechanical limitations and problems associated with prior art mats. In typical usage, the respective properties of the top sheet and the bottom pad together enable the whole mat to function so that--like a natural-grass-covered fairway--it imposes very little resistance as it readily yields to and accommodates the bottom-most portion--between the bottom of the ball and the underlying ground/base--of any fill, and reasonably well aligned golf club swing arc. Golf clubs that are swung through arcs which hit down before one's stance and rotation center, and would otherwise tend to dig into a natural earth base, or a typical practice-range mat, impact relatively softly and slide forward without appreciable loss of momentum, and allow the golfer to complete the somewhat mis-aligned swing-arc without discomfort and deterrence to future efforts.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
