The events leading up to the "patent pool"***(1) were a very complicated affair, and the pool, itself, basically involved both parties "buying into" Columbia's newly acquired (1901) Jones patent #688,739 (SEE:
http://www.google.com/patents?id=p9FuAA ... dq=688,739) covering the production of a wax based lateral recording system. This patent was actually what allowed Columbia to produce lateral cut wax disc masters, and was purchased by Columbia from Jones for $25,000 prior to the patent pool.
Columbia's first disc records are mentioned in this section of the Sarnoff's site's history of the Victor Talking Machine Co.:
FROM:
http://www.davidsarnoff.org/vtm-chapter5.html
"Up to the Fall of 1901, both Edison and Columbia stood firmly back of the cylinder principal as against the disc. .... However, Columbia was so impressed with the improved disc record that, as we have seen,
they introduced one of their own during the last quarter of 1901 under the name, "Columbia Disc Graphophone." It was not only a disc, but was also recorded by the Lateral Cut method ... and in styling was so close to the Victor product as to cause confusion. Further, it infringed the Berliner patent and Victor got an injunction....
Under this (cross-licensing agreement,) Columbia got what they needed from the Berliner patent, and Victor got what they needed from the Jones patent..."

***Footnote Added 6/12/07:
(1) The recording process initially patented by Berliner involved the use of wax coated zinc discs. The surface was etched by the recording stylus, and then the disc was immersed into an acid bath until the groove was burned to a sufficient depth. This not only produced an extremely noisy surface, but the method, itself, was unreliable. This process is described here:

This was replaced by the all-wax recording method, the invention of which was credited to Eldridge Johnson:
"By 1896, a solid wax disc had replaced Berliner's wax-coated zinc plate. History indicates that the developer of this advancement was Eldridge Reeves Johnson (later to become the founder of the Victor Talking Machine Company),
although he never applied for a patent. Bell and Tainter had earlier (1886) concluded that wax was the most suitable medium for any matrix, cylindrical or flat. Perkins, Kelly and Ward refer to the "Johnson all-wax process," which pretty well establishes its source. Jerrold Moore, in his biography of Fred Gaisberg, confirms Johnson's invention. One may note that the wax used initially by Johnson in the development of his recording medium was derived from cylinder records purchased direct from Edison!" (from above
site--http://www.cris.com/~oakapple/gasdisc/matrix1.htm.)
The important phrase in that paragraph is -- "although he never applied for a patent." It was
this improved wax recording process that the Columbia executives hired Jones (a former Berliner employee who had witnessed the process) to pursue a patent on--starting in 1897. After it was granted to Jones in December, 1901 Columbia immediately purchased it from him so they could initiate the production of discs.
Now, as far as the patent pool was concerned, it was NOT really a question of vertical vs. lateral recording. What the pool gave Victor was the right to use the wax based recording process--which Johnson had invented, but which Columbia had basically "stolen" from them. What it gave Columbia--among other things--was the right to use Berliner's playback method in which the lateral groove propelled the reproducer (or sound box) across the disc's surface.

Fortunately, all of this is well covered in the sites and books I've referred you to in my previous post ...so I'll say no more.
