Light flyweight division

On August 25, 2007, Calderón defeated Hugo Cázares by split decision to become the

and Lineal Light Flyweight Champion. Calderón entered the ring accompanied by a display of fireworks, before a crowd that featured several media personalities, including Oscar De La Hoya. The size difference between both pugilists was evident since the moment that they stood next to each other prior to the beginning of the fight. Early in the fight Calderón's tactic consisted of connecting fast consecutive combinations while avoiding Cázares' punches. With this strategy he managed to stun Cazares with uppercuts and straight punches. During the fight the crowd displayed support for Calderón, at one point chanting "Olé" when his adversary's punches missed. In the third round Cázares displayed a more fluid offensive, but in the fifth he presented a strategy that consisted of only throwing power punches which seemed to benefit Calderón. In the seventh round Ivan's offensive pace slowed which benefited Hugo who improved on the offensive aspect. In the eighth round Cázares connected several hard punches which led to Calderón to rely on holds to slow his offense, in this round Cázares scored a knockdown. In the ninth he was in a defensive stance, and during the last rounds he continued this pattern and only connected solidly in the tenth round while Cázares missed several of the punches he threw. At the conclusion of the fight the judges awarded scores of 116-111 for Cázares and 115-112 twice for Calderón. With this victory he became the eleventh Puerto Rican boxer to win multiple world championships and unified this championship with the minimum division's one until he vacated it following the announcement that he was going to continue in the light flyweight division. ''The Ring'' also recognized Calderón as their champion, dethroning Cázares. Calderón was successful on his first light flyweight title defense when he defeated Juan Esquer in a card that took place on December 1, 2007, in

. During the course of the fight Esquer was more active offensively. During the first four rounds of the match Calderón used his boxing skills to avoid being hit by the punches thrown by Esquer. From the fifth round onwards Calderón proceeded to exchange combinations of punches with Esquer, eventually gaining control of the fight's tempo. The fight lasted twelve rounds and Iván won the fight by unanimous decision with the judges awarding scores of 116–112, 118-110 and 115–113. Calderón's second defense in the light flyweight division took place on April 4, 2008, where he defeated Nelson Dieppa by unanimous decision. The three judges awarded him identical scores of 120–108.

in reference to his boxing style, which provoked "Olé" chants from the public. In the early stages, the fight's pattern was similar to the first meeting. Calderón relied on counter punching while boxing to avoid Cázares' offensive. Late in the first round, the challenger fell following a combination, but the referee declared that it was an accidental slip. In the following rounds, Cázares tried pressuring in the offensive, but Calderón continued boxing and held his opponent if approached. The challenger was momentarily stunned by an uppercut in the final seconds of the third episode. Cázares' technique in the next two rounds consisted of throwing punches to the body, while his offensive to the head was being stopped by his opponent's forearms. In the sixth round, Calderón focused on his defense, slowing the pace of his offensive. In the seventh episode, an accidental head clash opened a laceration in Calderón's forehead. Who was examined by the ringside doctor, after expressing that he was feeling disoriented. The physician recommended stopping the fight. Due to the circumstances, the outcome was decided by the judges' score cards, which favored Calderón 67-66 and 68-65 twice. Following the event, he announced his intention to participate in a unification match against one of the other light flyweight champions. Due to the nature of this injury, the Puerto Rico Boxing Commission prohibited Calderón participation in any card within 120 days. Two weeks after the contest, the wound was reopened and he underwent plastic surgery to prevent reinjury. On September 23, 2008, Peter Rivera announced that Calderón was expected to return between January and February 2009.

He subsequently stated that negotiations had been extended to Solís' representatives, but that those of Sosa still declined, citing that " eis a fighter that has always refused to fight with Iván. His managers don't want to sacrifice him and prefer to keep him in Mexico competing in soft fights."

On June 13, 2009, Calderón defended the championship against Rodel Mayol. During the first stage, both pugilists fought in the middle of the ring, while he focused on attacking the body while the challenger employed jabs. During the second and third rounds, Mayol pressured the offensive, managing to land a moderate number of punches. In the fourth round, Calderón began pursuing the offensive, while avoiding Mayol's punches. This continued in the following chapter, but a head clash opened another laceration on his forehead, he continued the contest, but was more aggressive from this point onwards. Calderón's corner tried to stop the bleeding, but the referee suspended the contest during the sixth round after these attempts proven unsuccessful. The fight was declared a technical draw, with both fighters receiving a 58-56 card while the third judge scored in 57-57. An immediate rematch was scheduled three months later. Calderón began this contest by effectively avoiding Mayol's constant attack, while throwing limited punches. This pattern continued during the following three rounds. In the fifth, Mayol connected his best punch of the fight, winning the round. To retaliate, Calderón became more aggressive, throwing more combinations. The seventh round began with exchanges from both boxers, but a head clash opens another laceration that stops the fight. The contest was declared a technical decision, with the judges offering scores of 68-65 twice for Calderón and 68-65 for Mayol.
