Matrix Map

<p>This Map uses “problem to be solved by the invention” and “means for solving the problem” as

aspects. Specifically, the Matrix Map shows the positioning of relevant key patents, together with

their right-holder (or applicant) and the corresponding patent number, for a set of problems to be

solved by the invention, in combination with a set of means for solving the problems. The former set

of problems includes: improvement of optical property; performance improvement of illuminated

ray; improvement of manufacturability; and other performance improvements. The latter set of

means for solving the problem includes: development of LED materials and structures; development

of methods for packaging; development of methods for manufacturing LED lamps; and development

of driving circuits.</p>

<p>

Generally, inventors are prompted to make an invention by problems to be solved by the

invention and means for solving the problem. By using these two aspects for analysis in a Matrix

Map, it is possible to carry out a meaningful analysis of information on patent rights as well as

technical information.</p>
