Untuk kasusnya gimana, bisa lihat blognya Satar aja di sini. Pokoknya summarynya Bajaj Auto mencoba mematenkan teknologi andalan mereka, 1 silinder 2 busi. Yang ternyata sudah di patenkan duluan secara internasional lewat US di tahun 1993 – 1994.
A misfire-detecting system for an internal combustion engine detects a value of the sparking voltage generated by the igniting device after generation of the ignition command signal, determines the duration of a discharge of a spark plug, based upon the detected sparking voltage, and determines whether or not a misfire has occurred in the engine, based upon the determined duration of the discharge. For example, the misfire-detecting system measures the duration of the discharge from the time of generation of the ignition command signal, based upon the detected sparking voltage, compares the measured duration of the discharge with a predetermined time period. When the measured duration is shorter than the predetermined time period, it is determined that a misfire has occurred in the engine.Penemu: Yuuichi Shimasaki, Masaki Kanehiro, Takuji Ishioka, Takashi Hisaki, Shigeru Maruyama, Shigetaka Kuroda, Masataka Chikamatsu, Hideaki Arai

On July 7, 2005, Bajaj was granted a patent with a priority date of July 16, 2002. The title of the patent application was “An improved Internal Combustion Engine working on four stroke principle.” The invention was called “DTS-i Technology” and it related to the
use of twin spark plugs located diametrically opposite to each other in a small displacement engine with the cylinder bore diameter ranging between 45 mm to 70 mm. Per Bajaj, this placement of the spark plugs enabled a better control over the ignition timing and lesser time was taken for the flame to travel during the process of combustion. The novelty also lay in the use of a sleeve to protect the spark plug which prevented exposure of the plugs to the lubricating oil.
Gimana tanggapan Bajaj?
Bajaj nanya ke induk Indianya, yang di Indonesia kan jualan saja. Ini ibarat nasi sudah
jadi bubur dimakan. Bajaj sudah jualan sekian banyak kok baru daftar patent?
Perlu diketahui juga, kalau akhirnya kasus Bajaj – TVS di India pun tidak jelas pemenangnya.
The use of two spark plugs in an IC engine with three valves was a prior art and therefore, the applicant cannot seek patent for the use of two spark plugs in an IC engine, and in order to avoid the said situation, the applicant has resorted to an art of deception by introducing a limitation of bore size to the US Honda patent with full knowledge that US Honda patent did not have any such limitation.
Di India pun tahu tentang US Honda patent, sehingga sebagai jalan tengah di India patentnya di limit saja ukuran-ukurannya.
