Abstract
The present paper focuses on some important requirements for understanding patent searchreports in view of their use for statistical analysis. It is pointed out and illustrated that thecomprehensiveness and the quality of a given search report may vary significantly as a function ofthe patent office drawing up the report. These differences imply consequences with respect to thesafe use and interpretation of the data. The authors stress that a sound analysis based on patentcitation data can only be performed in a meaningful way if the analyst has a minimum knowledgeof the underlying search reports.

Abstract
The investment in research and development (R&D) for semiconductor industry is never small as the technology cycle time (TCT) is relatively short comparing to other industries, thus a semiconductor company requires lots of technological innovations and capital offerings to maintain. The semiconductor industry contributes primarily part of the micro-electronic industries. Advancing technology and patent application are the centre of attention within the semiconductor sector. This research examines the relationship between patent quality and the profits a patent creates for a company in this selected field. This study distinguishes itself from prior research by including cross-sectional data, time series data to simultaneously collect and analyze. The study result shows that some indicators of patent quality are statistically significant to return on assets.
. 2 Patent citations are a good indicator of patent value or knowledge diffusion to the extend that the following conditions are satisfied: (i) cites are undertaken by independent assessors; (ii) patent examinations are given equal time and
Introduction Since Narin and his colleagues pioneered and further developed ‘patent citation analysis’ (Narin and Noma 1985 ; Narin et al. 1997 ; Narin and Olivastro 1998 ), an optimal method to analyze the interaction
