Ouch! I just read the Patent Office non-final action on the '148 patent and it does not look good for PTSC. All the major claims of the patent were rejected by the patent office as being obvious based on other patented material. I do not see how TPL can overcome the rejections as they are VERY well documented. Go to the site below and enter the "control number" 90/008,227 and click on "image file wrapper" and read it for yourself. Now may be the time to get out at this share price. PTSC could go far lower than .10c! Don't buy based on the paid promoters on this site and Agroacom! There are many boiler room operations pumping people to buy PTSC. http://portal.uspto.gov/external/portal/pair
